/*
|

|
|
* [Validation]
|
||
|
|
* The visitor code below will traverse the animation AST generated by the animation verb functions
|
||
|
|
* (the output is a tree of objects) and attempt to perform a series of validations on the data. The
|
||
|
|
* following corner-cases will be validated:
|
||
|
|
*
|
||
|
|
* 1. Overlap of animations
|
||
|
|
* Given that a CSS property cannot be animated in more than one place at the same time, it's
|
||
|
|
* important that this behavior is detected and validated. The way in which this occurs is that
|
||
|
|
* each time a style property is examined, a string-map containing the property will be updated with
|
||
|
|
* the start and end times for when the property is used within an animation step.
|
||
|
|
*
|
||
|
|
* If there are two or more parallel animations that are currently running (these are invoked by the
|
||
|
|
* group()) on the same element then the validator will throw an error. Since the start/end timing
|
||
|
|
* values are collected for each property then if the current animation step is animating the same
|
||
|
|
* property and its timing values fall anywhere into the window of time that the property is
|
||
|
|
* currently being animated within then this is what causes an error.
|
||
|
|
*
|
||
|
|
* 2. Timing values
|
||
|
|
* The validator will validate to see if a timing value of `duration delay easing` or
|
||
|
|
* `durationNumber` is valid or not.
|
||
|
|
*
|
||
|
|
* (note that upon validation the code below will replace the timing data with an object containing
|
||
|
|
* {duration,delay,easing}.
|
||
|
|
*
|
||
|
|
* 3. Offset Validation
|
||
|
|
* Each of the style() calls are allowed to have an offset value when placed inside of keyframes().
|
||
|
|
* Offsets within keyframes() are considered valid when:
|
||
|
|
*
|
||
|
|
* - No offsets are used at all
|
||
|
|
* - Each style() entry contains an offset value
|
||
|
|
* - Each offset is between 0 and 1
|
||
|
|
* - Each offset is greater to or equal than the previous one
|
||
|
|
*
|
||
|
|
* Otherwise an error will be thrown.

/*
|
||
|
|
* The code within this file aims to generate web-animations-compatible keyframes from Angular's
|
||
|
|
* animation DSL code.
|
||
|
|
*
|
||
|
|
* The code below will be converted from:
|
||
|
|
*
|
||
|
|
* ```
|
||
|
|
* sequence([
|
||
|
|
* style({ opacity: 0 }),
|
||
|
|
* animate(1000, style({ opacity: 0 }))
|
||
|
|
* ])
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* To:
|
||
|
|
* ```
|
||
|
|
* keyframes = [{ opacity: 0, offset: 0 }, { opacity: 1, offset: 1 }]
|
||
|
|
* duration = 1000
|
||
|
|
* delay = 0
|
||
|
|
* easing = ''
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* For this operation to cover the combination of animation verbs (style, animate, group, etc...) a
|
||
|
|
* combination of AST traversal and merge-sort-like algorithms are used.
|
||
|
|
*
|
||
|
|
* [AST Traversal]
|
||
|
|
* Each of the animation verbs, when executed, will return an string-map object representing what
|
||
|
|
* type of action it is (style, animate, group, etc...) and the data associated with it. This means
|
||
|
|
* that when functional composition mix of these functions is evaluated (like in the example above)
|
||
|
|
* then it will end up producing a tree of objects representing the animation itself.
|
||
|
|
*
|
||
|
|
* When this animation object tree is processed by the visitor code below it will visit each of the
|
||
|
|
* verb statements within the visitor. And during each visit it will build the context of the
|
||
|
|
* animation keyframes by interacting with the `TimelineBuilder`.
|
||
|
|
*
|
||
|
|
* [TimelineBuilder]
|
||
|
|
* This class is responsible for tracking the styles and building a series of keyframe objects for a
|
||
|
|
* timeline between a start and end time. The builder starts off with an initial timeline and each
|
||
|
|
* time the AST comes across a `group()`, `keyframes()` or a combination of the two within a
|
||
|
|
* `sequence()` then it will generate a sub timeline for each step as well as a new one after
|
||
|
|
* they are complete.
|
||
|
|
*
|
||
|
|
* As the AST is traversed, the timing state on each of the timelines will be incremented. If a sub
|
||
|
|
* timeline was created (based on one of the cases above) then the parent timeline will attempt to
|
||
|
|
* merge the styles used within the sub timelines into itself (only with group() this will happen).
|
||
|
|
* This happens with a merge operation (much like how the merge works in mergeSort) and it will only
|
||
|
|
* copy the most recently used styles from the sub timelines into the parent timeline. This ensures
|
||
|
|
* that if the styles are used later on in another phase of the animation then they will be the most
|
||
|
|
* up-to-date values.
|
||
|
|
*
|
||
|
|
* [How Missing Styles Are Updated]
|
||
|
|
* Each timeline has a `backFill` property which is responsible for filling in new styles into
|
||
|
|
* already processed keyframes if a new style shows up later within the animation sequence.
|
||
|
|
*
|
||
|
|
* ```
|
||
|
|
* sequence([
|
||
|
|
* style({ width: 0 }),
|
||
|
|
* animate(1000, style({ width: 100 })),
|
||
|
|
* animate(1000, style({ width: 200 })),
|
||
|
|
* animate(1000, style({ width: 300 }))
|
||
|
|
* animate(1000, style({ width: 400, height: 400 })) // notice how `height` doesn't exist anywhere
|
||
|
|
* else
|
||
|
|
* ])
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* What is happening here is that the `height` value is added later in the sequence, but is missing
|
||
|
|
* from all previous animation steps. Therefore when a keyframe is created it would also be missing
|
||
|
|
* from all previous keyframes up until where it is first used. For the timeline keyframe generation
|
||
|
|
* to properly fill in the style it will place the previous value (the value from the parent
|
||
|
|
* timeline) or a default value of `*` into the backFill map.
|
||
|
|
*
|
||
|
|
* When a sub-timeline is created it will have its own backFill property. This is done so that
|
||
|
|
* styles present within the sub-timeline do not accidentally seep into the previous/future timeline
|
||
|
|
* keyframes
|
||
|
|
*
|
||
|
|
* [Validation]
|
||
|
|
* The code in this file is not responsible for validation. That functionality happens with within
|
||
|
|
* the `AnimationValidatorVisitor` code.

When the keyframe is stretched then it means that the delay before the animation
|
||
|
|
starts is gone. Instead the first keyframe is placed at the start of the animation
|
||
|
|
and it is then copied to where it starts when the original delay is over. This basically
|
||
|
|
means nothing animates during that delay, but the styles are still rendered. For this
|
||
|
|
to work the original offset values that exist in the original keyframes must be "warped"
|
||
|
|
so that they can take the new keyframe + delay into account.
