Since the start/end timing\n * values are collected for each property then if the current animation step is animating the same\n * property and its timing values fall anywhere into the window of time that the property is\n * currently being animated within then this is what causes an error.\n *\n * 2. Timing values\n * The validator will validate to see if a timing value of `duration delay easing` or\n * `durationNumber` is valid or not.\n *\n * (note that upon validation the code below will replace the timing data with an object containing\n * {duration,delay,easing}.\n *\n * 3.

This means\n * that when functional composition mix of these functions is evaluated (like in the example above)\n * then it will end up producing a tree of objects representing the animation itself.\n *\n * When this animation object tree is processed by the visitor code below it will visit each of the\n * verb statements within the visitor. And during each visit it will build the context of the\n * animation keyframes by interacting with the `TimelineBuilder`.\n *\n * [TimelineBuilder]\n * This class is responsible for tracking the styles and building a series of keyframe objects for a\n * timeline between a start and end time. The builder starts off with an initial timeline and each\n * time the AST comes across a `group()`, `keyframes()` or a combination of the two within a\n * `sequence()` then it will generate a sub timeline for each step as well as a new one after\n * they are complete.\n *\n * As the AST is traversed, the timing state on each of the timelines will be incremented. If a sub\n * timeline was created (based on one of the cases above) then the parent timeline will attempt to\n * merge the styles used within the sub timelines into itself (only with group() this will happen).\n * This happens with a merge operation (much like how the merge works in mergeSort) and it will only\n * copy the most recently used styles from the sub timelines into the parent timeline. This ensures\n * that if the styles are used later on in another phase of the animation then they will be the most\n * up-to-date values.\n *\n * [How Missing Styles Are Updated]\n * Each timeline has a `backFill` property which is responsible for filling in new styles into\n * already processed keyframes if a new style shows up later within the animation sequence.\n *\n * ```ts\n * sequence([\n * style({ width: 0 }),\n * animate(1000, style({ width: 100 })),\n * animate(1000, style({ width: 200 })),\n * animate(1000, style({ width: 300 }))\n * animate(1000, style({ width: 400, height: 400 })) // notice how `height` doesn't exist anywhere\n * else\n * ])\n * ```\n *\n * What is happening here is that the `height` value is added later in the sequence, but is missing\n * from all previous animation steps. Therefore when a keyframe is created it would also be missing\n * from all previous keyframes up until where it is first used. For the timeline keyframe generation\n * to properly fill in the style it will place the previous value (the value from the parent\n * timeline) or a default value of `*` into the backFill map.\n *\n * When a sub-timeline is created it will have its own backFill property.

    Dropdown

    \n

    \n This is our custom dropdown component which wraps a mat-select component as its core part.\n

    \n

    For usage details check out the DropdownConfiguration interface in the component.

    \n

    \n Note that while the mat-select needs to be overwritten by global styles, we keep them in the\n dropdown.component.scss. This is acchieved by importing the component styles in the global\n stylessheet and applying them to the host element in the @Component annotation in\n dropdown.component.ts. This is done because wrapping the dropdown styles inside the :host\n selector does not result in overwriting global Material styles\n

    Standard Modal/Dialog

    \n

    \n Öffne den Dialog per Klick auf den Button, um einen Standard-Dialog auf Basis unserer\n modal-Klassen zu sehen.\n

    \n

    \n \n Unbedingt beachten: Angular Material ermöglicht es dem dialog ein config-Objekt zu\n übergeben.\n \n

    \n

    Liste der möglichen Properties:

    \n

    \n material.angular.io/components/dialog/api#MatDialogConfig\n

    \n

    \n Diese Möglichkeit sollte genutzt werden, um z.B. unerwünschten Auto-focus zu vermeinden, wie\n im folgenden Snippet. Angaben, wie width, die auch im CSS angegeben werden können bitte nur\n in Ausnahmefällen verwenden. Der Ursprung des Werts ist sonst schwer zu finden und in\n Dev-Tools gar nicht.\n

    \n 
    \n    {{openDialog.toString()}}
    \n
    \n
    \n \n
    \n
    \n

    Infobox-Dialog

    \n

    \n Die Inhalte des Infobox-Dialog sind flexibel und müssen per infobox-dialog.service übergeben\n werden.\n

    \n

    Folgend die Properties des Beispiels.

    \n 
    \n    {{openInfoboxDialog.toString()}}
    \n
    \n
    \n \n
    \n
    \n

    Error-Dialog

    \n

    \n Die Inhalte des Error-Dialog sind flexibel, je nach Error-Code aus dem Backend werden die\n entsprechenden Inhalte übergeben.\n

    \n

    \n Die aktuellsten errorCode sind im node-server in der Datei src/errorcodes.js zu\n finden. Eine Anleitung zum Error Handling und dem Aufbau der Error-Codes ist\n hier in Confluence\n zu finden.\n

    \n

    Folgend die Properties des Beispiels.

    \n 
    \n    {{openErrorDialog.toString()}}
    \n

    \n In der location sollte die Klasse/Funktion des ErrorDialog Aufrufs notiert werden.\n

    \n

    \n Standardmäßig wird als devInfo \"error.message\" - falls verfügbar - übergeben.\n Ansonsten sollte hier ein aktueller Zustand, wie z.B. 'res.status === FAILED' übergeben\n werden.\n

    \n\n

    \n In der puplicInfo sollte mindestens einer der beiden folgenden Textblöcken verwendet\n werden:\n

    \n     \n

    \n debug sollte nur für die Fehlersuche auf true gestellt werden, für einen Merge immer\n auf false.\n

    \n

    \n autoFocus muss immer false sein, da sonst das erste tabbable Element auf Fokus\n gesetzt & gehighlighted wird.\n

    Angular Material Buttons

    \n

    \n Das Prinzip der Angular material Buttons wurde auf die Bedürfnisse unserer Anwendung\n übertragen:\n https://material.angular.io/components/button\n

    \n

    \n Ein Button wir standardmäßig und ganz normal per HTML mit den unterschiedlichen Attribute\n Definitions und Klassenangaben integriert. Dabei müssen keine Veränderungen am CSS\n vorgenommen werden, um Farbe oder Größe individuell anzupassen..

    Beispiele (ohne\n die Einfärbung durch ein Theme):\n

    \n\n \n\n \n 
    {{ code_matbutton }}
    \n     \n\n \n\n \n 
    {{ code_matflatbutton }}
    \n     \n\n \n \n 
    {{ code_matstrokedbutton }}
    \n     \n\n

     

    \n

    \n Farben:\n

    \n\n

    \n Jeder Button kann dann per Attribute Definitions eingefärbt werden, in den\n 4 verfügbaren Farben (accent, primary, warn, disabled). Bei der disabled\n Variante sind zudem alle Stati/Funktionalitäten (Hover, Active, Klick-Ripple-Effekt)\n deaktiviert.

    Beispiel color=\"accent\":\n

    \n \n\n \n 
    {{ code_matflatbutton_attributecolors_accent }}
    \n     \n



    Beispiel color=\"primary\":

    \n \n\n \n 
    {{ code_matflatbutton_attributecolors_primary }}
    \n     \n\n

     

    \n

    \n Varianten:\n

    \n\n

    \n Insgesamt stehen 4 verschiedene Varianten an Buttons zur Verfügung (jeweils\n mit/ohne Icon):\n

    \n\n
      \n
    • \n mat-flat-button -> Flacher Button mit flächigem farbigen\n Hintergrund\n
      • \n
    • \n mat-stroked-button -> Outline Button mit farbiger border\n
      • \n
    • \n mat-button -> Button-Link mit farbigem Text und Ripple-Effekt bei\n Klick\n
      • \n
    • \n mat-icon-button -> Button ohne Texte, entweder mit oder ohne\n Hintergrund (siehe \"Only Icons\")\n
      • \n
    \n\n

     

    \n

    \n Icons:\n

    \n\n

    \n Zudem kann jeder Button (außer der mat-icon-button der immer eines dabei hat) mit einem\n Icon bzw. Material Icon (https://material.angular.io/components/icon/overview\n und\n https://fonts.google.com/icons)versehen werden.

    Beispiel:\n

    \n \n\n \n 
    {{ code_matflatbutton_icon }}
    \n     \n\n

     

    \n

    \n Only Icons :\n

    \n\n

    mat-icon-button ohne Hintergrund.

    Beispiel:

    \n\n \n\n \n 
    {{ code_maticonbutton }}
    \n     \n

     

    \n\n

    \n mat-icon button mit Hintergrund (hier muss class=\"icon-button-bg\"\n hinzugefügt werden).

    Beispiel:\n

    \n\n \n\n \n 
    {{ code_maticonbutton_bg }}
    \n     \n\n

     

    \n

    \n Button Sizes:\n

    \n

    \n Zudem gibt es 4 verschiedene Buttongrößen (hier muss class=\"button-size-xl\" hinzugefügt\n werden).

    Beispiel:\n

    \n\n \n \n 
    {{ code_matbutton_size }}
    \n     \n\n

    \n
    \n

    Basic Tooltips

    \n

    \n Die Tooltips aus Angular Material (https://material.angular.io/components/tooltip/overview)\n werden über folgende drei Optionen gesteuert:\n

    \n \n matTooltip=\"Tooltip Erklärungstext\"
    \n matTooltipClass=\"tooltip-icon | tooltip-definition | tooltip-interactive\"
    \n matTooltipPosition=\"above | below | left | right | before | after\"
    \n     \n

    \n

    \n

    Icon Tooltip

    \n

    \n Ein Icon-Tooltip wird verwendet, um die Aktion oder den Namen einer interaktiven\n Icon-Schaltfläche zu verdeutlichen. Dieser besteht nur aus wenigen Worten, bestenfalls nur\n einem (maximal 2-3).\n

    \n

    \n

    Definition Tooltips

    \n

    \n Der Definitionstooltip bietet zusätzliche Hilfe oder definiert ein Element oder einen\n Begriff.\n

    \n
    \n
    \n \n \n Icon & above\n \n info\n \n \n \n Icon & below\n \n info\n \n \n \n Definition & left\n \n info\n \n \n \n Definition & right\n \n info\n \n \n \n
    \n\n
    \n

    HTML/Interactive Tooltips

    \n

    \n ! Bisherige Lösung mittels ng-tippy ist veraltet. Der Code dafür ist noch im auskommentiert\n hier im Templat enthalten. Bei Bedarf könnte er vielleicht wiederverwendet werden, falls\n künftig tippy.js direkt verwendet wrden soll.\n

    Typography-Levels

    \n

    \n Unsere Standardgrößen für Fonts sind im Frontend über Typography-Levels umgesetzt, wie sie\n Angular-Material verwendet.\n

    \n

    \n Sie sind unterteilt in Heading- und Body-Levels. Heading- und Body-Levels unterscheiden sich\n grundsätzlich in line-heights und font-weights.\n

    \n

    \n Der Einsatz der Levels kann einerseits über die zuweisung zu Angular Material\n Standard-Levels erfolgen, sodass Material unsere levels in seine Standard-Klassen\n miteinbeiht. Andererseits können wir sie per Mixins einsetzen: @mixin\n get-level-styles($level-name, $important: '').\n

bound to the trigger changes.\n *\n * @param name An identifying string.\n * @param definitions An animation definition object, containing an array of\n * [`state()`](api/animations/state) and `transition()` declarations.\n *\n * @return An object that encapsulates the trigger data.\n *\n * @usageNotes\n * Define an animation trigger in the `animations` section of `@Component` metadata.\n * In the template, reference the trigger by name and bind it to a trigger expression that\n * evaluates to a defined animation state, using the following format:\n *\n * `[@triggerName]=\"expression\"`\n *\n * Animation trigger bindings convert all values to strings, and then match the\n * previous and current values against any linked transitions.\n * Booleans can be specified as `1` or `true` and `0` or `false`.\n *\n * ### Usage Example\n *\n * The following example creates an animation trigger reference based on the provided\n * name value.\n * The provided animation value is expected to be an array consisting of state and\n * transition declarations.\n *\n * ```ts\n * @Component({\n * selector: \"my-component\",\n * templateUrl: \"my-component-tpl.html\",\n * animations: [\n * trigger(\"myAnimationTrigger\", [\n * state(...),\n * state(...),\n * transition(...),\n * transition(...)\n * ])\n * ]\n * })\n * class MyComponent {\n * myStatusExp = \"something\";\n * }\n * ```\n *\n * The template associated with this component makes use of the defined trigger\n * by binding to an element within its template code.\n *\n * ```html\n * \n *
    ...
    \n * ```\n *\n * ### Using an inline function\n * The `transition` animation method also supports reading an inline function which can decide\n * if its associated animation should be run.\n *\n * ```ts\n * // this method is run each time the `myAnimationTrigger` trigger value changes.\n * function myInlineMatcherFn(fromState: string, toState: string, element: any, params: {[key:\n string]: any}): boolean {\n * // notice that `element` and `params` are also available here\n * return toState == 'yes-please-animate';\n * }\n *\n * @Component({\n * selector: 'my-component',\n * templateUrl: 'my-component-tpl.html',\n * animations: [\n * trigger('myAnimationTrigger', [\n * transition(myInlineMatcherFn, [\n * // the animation sequence code\n * ]),\n * ])\n * ]\n * })\n * class MyComponent {\n * myStatusExp = \"yes-please-animate\";\n * }\n * ```\n *\n * ### Disabling Animations\n * When true, the special animation control binding `@.disabled` binding prevents\n * all animations from rendering.\n * Place the `@.disabled` binding on an element to disable\n * animations on the element itself, as well as any inner animation triggers\n * within the element.\n *\n * The following example shows how to use this feature:\n *\n * ```angular-ts\n * @Component({\n * selector: 'my-component',\n * template: `\n *

This is also the case for when a sub animation is\n * queried by a parent and then later animated using `animateChild()`.\n *\n * ### Detecting when an animation is disabled\n * If a region of the DOM (or the entire application) has its animations disabled, the animation\n * trigger callbacks still fire, but for zero seconds. When the callback fires, it provides\n * an instance of an `AnimationEvent`. If animations are disabled,\n * the `.disabled` flag on the event is true.\n *\n * @publicApi\n */\nfunction trigger(name, definitions) {\n return { type: AnimationMetadataType.Trigger, name, definitions, options: {} };\n}\n/**\n * Defines an animation step that combines styling information with timing information.\n *\n * @param timings Sets `AnimateTimings` for the parent animation.\n * A string in the format \"duration [delay] [easing]\".\n * - Duration and delay are expressed as a number and optional time unit,\n * such as \"1s\" or \"10ms\" for one second and 10 milliseconds, respectively.\n * The default unit is milliseconds.\n * - The easing value controls how the animation accelerates and decelerates\n * during its runtime.

    \n *\n * Be careful about entering end leaving elements as their transitions present a common\n * pitfall for developers.\n *\n * Note that when an element with a trigger enters the DOM its `:enter` transition always\n * gets executed, but its `:leave` transition will not be executed if the element is removed\n * alongside its parent (as it will be removed \"without warning\" before its transition has\n * a chance to be executed, the only way that such transition can occur is if the element\n * is exiting the DOM on its own).\n *\n *\n *
    \n *\n * ### Animating to a Final State\n *\n * If the final step in a transition is a call to `animate()` that uses a timing value\n * with no `style` data, that step is automatically considered the final animation arc,\n * for the element to reach the final state, in such case Angular automatically adds or removes\n * CSS styles to ensure that the element is in the correct final state.\n *\n *\n * ### Usage Examples\n *\n * - Transition animations applied based on\n * the trigger's expression value\n *\n * ```html\n *
    \n * ...\n *

For example:\n *\n * ```ts\n * query(':self, .record:enter, .record:leave, @subTrigger', [...])\n * ```\n *\n * The `query()` function collects multiple elements and works internally by using\n * `element.querySelectorAll`. Use the `limit` field of an options object to limit\n * the total number of items to be collected. For example:\n *\n * ```js\n * query('div', [\n * animate(...),\n * animate(...)\n * ], { limit: 1 })\n * ```\n *\n * By default, throws an error when zero items are found. Set the\n * `optional` flag to ignore this error. For example:\n *\n * ```js\n * query('.some-element-that-may-not-be-there', [\n * animate(...),\n * animate(...)\n * ], { optional: true })\n * ```\n *\n * ### Entering and Leaving Elements\n *\n * Not all elements can be queried via the `:enter` and `:leave` tokens, the only ones\n * that can are those that Angular assumes can enter/leave based on their own logic\n * (if their insertion/removal is simply a consequence of that of their parent they\n * should be queried via a different token in their parent's `:enter`/`:leave` transitions).\n *\n * The only elements Angular assumes can enter/leave based on their own logic (thus the only\n * ones that can be queried via the `:enter` and `:leave` tokens) are:\n * - Those inserted dynamically (via `ViewContainerRef`)\n * - Those that have a structural directive (which, under the hood, are a subset of the above ones)\n *\n *
    \n *\n * Note that elements will be successfully queried via `:enter`/`:leave` even if their\n * insertion/removal is not done manually via `ViewContainerRef`or caused by their structural\n * directive (e.g. they enter/exit alongside their parent).\n *\n *
    \n *\n *
    \n *\n * There is an exception to what previously mentioned, besides elements entering/leaving based on\n * their own logic, elements with an animation trigger can always be queried via `:leave` when\n * their parent is also leaving.\n *\n *
    \n *\n * ### Usage Example\n *\n * The following example queries for inner elements and animates them\n * individually using `animate()`.\n *\n * ```angular-ts\n * @Component({\n * selector: 'inner',\n * template: `\n *

  • \n * {{i}}/{{users.length}}. {{user}} default\n *
    • \n * ```\n *\n * The following exported values can be aliased to local variables:\n *\n * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).\n * - `ngForOf: NgIterable`: The value of the iterable expression. Useful when the expression is\n * more complex then a property access, for example when using the async pipe (`userStreams |\n * async`).\n * - `index: number`: The index of the current item in the iterable.\n * - `count: number`: The length of the iterable.\n * - `first: boolean`: True when the item is the first item in the iterable.\n * - `last: boolean`: True when the item is the last item in the iterable.\n * - `even: boolean`: True when the item has an even index in the iterable.\n * - `odd: boolean`: True when the item has an odd index in the iterable.\n *\n * ### Change propagation\n *\n * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:\n *\n * * When an item is added, a new instance of the template is added to the DOM.\n * * When an item is removed, its template instance is removed from the DOM.\n * * When items are reordered, their respective templates are reordered in the DOM.\n *\n * Angular uses object identity to track insertions and deletions within the iterator and reproduce\n * those changes in the DOM.

    \n * Content to render when value is null.\n * ```\n *\n * @usageNotes\n *\n * The `*ngIf` directive is most commonly used to conditionally show an inline template,\n * as seen in the following example.\n * The default `else` template is blank.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfSimple'}\n *\n * ### Showing an alternative template using `else`\n *\n * To display a template when `expression` evaluates to false, use an `else` template\n * binding as shown in the following example.\n * The `else` binding points to an `` element labeled `#elseBlock`.\n * The template can be defined anywhere in the component view, but is typically placed right after\n * `ngIf` for readability.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfElse'}\n *\n * ### Using an external `then` template\n *\n * In the previous example, the then-clause template is specified inline, as the content of the\n * tag that contains the `ngIf` directive. You can also specify a template that is defined\n * externally, by referencing a labeled `` element. When you do this, you can\n * change which template to use at runtime, as shown in the following example.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}\n *\n * ### Storing a conditional result in a variable\n *\n * You might want to show a set of properties from the same object. If you are waiting\n * for asynchronous data, the object can be undefined.\n * In this case, you can use `ngIf` and store the result of the condition in a local\n * variable as shown in the following example.\n *\n * {@example common/ngIf/ts/module.ts region='NgIfAs'}\n *\n * This code uses only one `AsyncPipe`, so only one subscription is created.\n * The conditional statement stores the result of `userStream|async` in the local variable `user`.\n * You can then bind the local `user` repeatedly.\n *\n * The conditional displays the data only if `userStream` returns a value,\n * so you don't need to use the\n * safe-navigation-operator (`?.`)\n * to guard against null values when accessing properties.\n * You can display an alternative template while waiting for the data.\n *\n * ### Shorthand syntax\n *\n * The shorthand syntax `*ngIf` expands into two separate template specifications\n * for the \"then\" and \"else\" clauses. For example, consider the following shorthand statement,\n * that is meant to show a loading page while waiting for data to be loaded.\n *\n * ```html\n *
    \n * ...\n *
    \n *\n * \n *
    Loading...
    \n *     \n * ```\n *\n * You can see that the \"else\" clause references the ``\n * with the `#loading` label, and the template for the \"then\" clause\n * is provided as the content of the anchor element.\n *\n * However, when Angular expands the shorthand syntax, it creates\n * another `` tag, with `ngIf` and `ngIfElse` directives.\n * The anchor element containing the template for the \"then\" clause becomes\n * the content of this unlabeled `` tag.\n *\n * ```html\n * \n *
    \n * ...\n *
    \n *     \n *\n * \n *
    Loading...
    \n *     \n * ```\n *\n * The presence of the implicit template object has implications for the nesting of\n * structural directives.

### Format examples\n *\n * These examples transform a date into various formats,\n * assuming that `dateObj` is a JavaScript `Date` object for\n * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,\n * given in the local time for the `en-US` locale.\n *\n * ```\n * {{ dateObj | date }} // output is 'Jun 15, 2015'\n * {{ dateObj | date:'medium' }} // output is 'Jun 15, 2015, 9:43:11 PM'\n * {{ dateObj | date:'shortTime' }} // output is '9:43 PM'\n * {{ dateObj | date:'mm:ss' }} // output is '43:11'\n * {{ dateObj | date:\"MMM dd, yyyy 'at' hh:mm a\" }} // output is 'Jun 15, 2015 at 09:43 PM'\n * ```\n *\n * ### Usage example\n *\n * The following component uses a date pipe to display the current date in different formats.\n *\n * ```angular-ts\n * @Component({\n * selector:
