Definition
Important

Calculates a value that represents the current value of the property being animated, as determined by the host animation.
protected:
abstract char GetCurrentValueCore(char defaultOriginValue, char defaultDestinationValue, System::Windows::Media::Animation::AnimationClock ^ animationClock);
protected abstract char GetCurrentValueCore (char defaultOriginValue, char defaultDestinationValue, System.Windows.Media.Animation.AnimationClock animationClock);
abstract member GetCurrentValueCore : char * char * System.Windows.Media.Animation.AnimationClock -> char
Protected MustOverride Function GetCurrentValueCore (defaultOriginValue As Char, defaultDestinationValue As Char, animationClock As AnimationClock) As Char
Parameters
- defaultOriginValue
- Char
The suggested origin value, used if the animation does not have its own explicitly set start value.
- defaultDestinationValue
- Char
The suggested destination value, used if the animation does not have its own explicitly set end value.
- animationClock
- AnimationClock
An AnimationClock that generates the CurrentTime or CurrentProgress used by the host animation.
Returns
The calculated value of the property, as determined by the current animation.
Remarks
The value of the defaultOriginValue
parameter depends on the animation's position in the composition chain:
If the animation is in the first position in a composition chain and it replaces another animation,
defaultOriginValue
is the output of that animation at the time it was replaced.If the animation is in the first position in a composition chain and no animation exists to replace,
defaultOriginValue
is the base value of the animated property.If this animation is not in the first position of a composition chain, then
defaultOriginValue
is the value that is returned by the previous animation in the composition chain that has an AnimationClock that is not Stopped.
The value of the defaultDestinationValue
parameter depends on whether there is a previous property Trigger composition layer.
If there is a previous property Trigger composition layer,
defaultDestinationValue
is the output from that layer.If there is no previous composition layer,
defaultDestinationValue
is the base value of the property that you are animating.
