Struct SubchannelAnimationInstance 

pub struct SubchannelAnimationInstance { /* private fields */ }

The server instance of the animations of sub-channels of one property: it evaluates the animation of each sub-channel and writes the result into the components of the current value of the property.

The inner instances are initialized with the property itself, so their invalidation marks this instance (the animation of the property) dirty.

Implementations

impl SubchannelAnimationInstance

pub fn new( target: ServerObjectId, components: Vec<usize>, instance: Rc<dyn IAnimationInstance>, ) -> Rc<SubchannelAnimationInstance>

An instance with one sub-channel, components of the property, animated by instance.

pub fn components(&self) -> Vec<Vec<usize>>

The component sets of the running sub-channels.

Trait Implementations

impl IAnimationInstance for SubchannelAnimationInstance

fn attach_controller(&self, controller: ServerObjectId)

Every running sub-channel is put under the controller.

fn target_object(&self) -> ServerObjectId

The object whose property is animated.

fn resolve(&self, compositor: &Rc<ServerCompositor>)

Resolves the server objects the instance refers to by id, on the compositor that drives it. Called once, on the server, before the instance is initialized; an instance that refers to no object needs nothing.

fn evaluate( &self, now: Duration, current_value: ExpressionVariant, ) -> ExpressionVariant

The value of the animation at now.

fn initialize( &self, started_at: Duration, starting_value: ExpressionVariant, property: &'static CompositionProperty, )

Attaches the instance to the property it animates.

fn activate(&self)

fn deactivate(&self)

fn invalidate(&self)

fn value_on_stop( &self, current_value: ExpressionVariant, ) -> Option<ExpressionVariant>

The value the animated property is set to when the animation is stopped by StopAnimation (its stop behavior), given the current value of the property; None leaves the current value.

fn release_completion(&self)

Tells the batches the animation belongs to that it is over (it is stopped, replaced or its target is disposed). Releasing again does nothing; an animation that belongs to no batch does nothing.

fn as_subchannel(&self) -> Option<&SubchannelAnimationInstance>

The instance as an animation of components of its property (Offset.X), if it is one: such animations of one property are merged on the server.

impl IServerClockItem for SubchannelAnimationInstance

fn on_tick(&self)

The inner instances are on the clock themselves.
