Constructor Detail

AnimatablePathDataValue

protected AnimatablePathDataValue(AnimationTarget target)

Creates a new, uninitialized AnimatablePathDataValue.

AnimatablePathDataValue

public AnimatablePathDataValue(AnimationTarget target,
                               short[] commands,
                               float[] parameters)

Creates a new AnimatablePathDataValue.

Method Detail

interpolate

public AnimatableValue interpolate(AnimatableValue result,
                                   AnimatableValue to,
                                   float interpolation,
                                   AnimatableValue accumulation,
                                   int multiplier)

Performs interpolation to the given value.

Specified by:

interpolate in class AnimatableValue

Parameters:

result - the object in which to store the result of the interpolation, or null if a new object should be created

to - the value this value should be interpolated towards, or null if no actual interpolation should be performed

interpolation - the interpolation distance, 0 <= interpolation <= 1

accumulation - an accumulation to add to the interpolated value

multiplier - an amount the accumulation values should be multiplied by before being added to the interpolated value

getCommands

public short[] getCommands()

Returns the array of path data commands.

getParameters

public float[] getParameters()

Returns the array of path data parameters.

canPace

public boolean canPace()

Returns whether two values of this type can have their distance computed, as needed by paced animation.

Specified by:

canPace in class AnimatableValue

distanceTo

public float distanceTo(AnimatableValue other)

Returns the absolute distance between this value and the specified other value.

Specified by:

distanceTo in class AnimatableValue

getZeroValue

public AnimatableValue getZeroValue()

Returns a zero value of this AnimatableValue's type.

Specified by:

getZeroValue in class AnimatableValue

toStringRep

public String toStringRep()

Returns a string representation of this object.

Overrides:
