Overlap of animations\n * Given that a CSS property cannot be animated in more than one place at the same time, it's\n * important that this behavior is detected and validated.

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. Offset Validation\n * Each of the style() calls are allowed to have an offset value when placed inside of keyframes().\n * Offsets within keyframes() are considered valid when:\n *\n * - No offsets are used at all\n * - Each style() entry contains an offset value\n * - Each offset is between 0 and 1\n * - Each offset is greater to or equal than the previous one\n *\n * Otherwise an error will be thrown.\n */\nfunction buildAnimationAst(driver, metadata, errors, warnings) {\n return new AnimationAstBuilderVisitor(driver).build(metadata, errors, warnings);\n}\nconst ROOT_SELECTOR = '';\nclass AnimationAstBuilderVisitor {\n constructor(_driver) {\n this._driver = _driver;\n }\n build(metadata, errors, warnings) {\n const context = new AnimationAstBuilderContext(errors);\n this._resetContextStyleTimingState(context);\n const ast = (visitDslNode(this, normalizeAnimationEntry(metadata), context));\n if (typeof ngDevMode === 'undefined' || ngDevMode) {\n if (context.unsupportedCSSPropertiesFound.size) {\n pushUnrecognizedPropertiesWarning(warnings, [\n ...context.unsupportedCSSPropertiesFound.keys(),\n ]);\n }\n }\n return ast;\n }\n _resetContextStyleTimingState(context) {\n context.currentQuerySelector = ROOT_SELECTOR;\n context.collectedStyles = new Map();\n context.collectedStyles.set(ROOT_SELECTOR, new Map());\n context.currentTime = 0;\n }\n visitTrigger(metadata, context) {\n let queryCount = (context.queryCount = 0);\n let depCount = (context.depCount = 0);\n const states = [];\n const transitions = [];\n if (metadata.name.charAt(0) == '@') {\n context.errors.push(invalidTrigger());\n }\n metadata.definitions.forEach((def) => {\n this._resetContextStyleTimingState(context);\n if (def.type == AnimationMetadataType.State) {\n const stateDef = def;\n const name = stateDef.name;\n name\n .toString()\n .split(/\\s*,\\s*/)\n .forEach((n) => {\n stateDef.name = n;\n states.push(this.visitState(stateDef, context));\n });\n stateDef.name = name;\n }\n else if (def.type == AnimationMetadataType.Transition) {\n const transition = this.visitTransition(def, context);\n queryCount += transition.queryCount;\n depCount += transition.depCount;\n transitions.push(transition);\n }\n else {\n context.errors.push(invalidDefinition());\n }\n });\n return {\n type: AnimationMetadataType.Trigger,\n name: metadata.name,\n states,\n transitions,\n queryCount,\n depCount,\n options: null,\n };\n }\n visitState(metadata, context) {\n const styleAst = this.visitStyle(metadata.styles, context);\n const astParams = (metadata.options && metadata.options.params) || null;\n if (styleAst.containsDynamicStyles) {\n const missingSubs = new Set();\n const params = astParams || {};\n styleAst.styles.forEach((style) => {\n if (style instanceof Map) {\n style.forEach((value) => {\n extractStyleParams(value).forEach((sub) => {\n if (!params.hasOwnProperty(sub)) {\n missingSubs.add(sub);\n }\n });\n });\n }\n });\n if (missingSubs.size) {\n context.errors.push(invalidState(metadata.name, [...missingSubs.values()]));\n }\n }\n return {\n type: AnimationMetadataType.State,\n name: metadata.name,\n style: styleAst,\n options: astParams ?

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 * ```\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. This is done so that\n * styles present within the sub-timeline do not accidentally seep into the previous/future timeline\n * keyframes\n *\n * [Validation]\n * The code in this file is not responsible for validation. That functionality happens with within\n * the `AnimationValidatorVisitor` code.\n */\nfunction buildAnimationTimelines(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles = new Map(), finalStyles = new Map(), options, subInstructions, errors = []) {\n return new AnimationTimelineBuilderVisitor().buildKeyframes(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles, finalStyles, options, subInstructions, errors);\n}\nclass AnimationTimelineBuilderVisitor {\n buildKeyframes(driver, rootElement, ast, enterClassName, leaveClassName, startingStyles, finalStyles, options, subInstructions, errors = []) {\n subInstructions = subInstructions || new ElementInstructionMap();\n const context = new AnimationTimelineContext(driver, rootElement, subInstructions, enterClassName, leaveClassName, errors, []);\n context.options = options;\n const delay = options.delay ?
