    public abstract class AnimatableValue

extends java.lang.Object

An abstract class for values in the animation engine.

Field Summary
`protected static java.text.DecimalFormat` `decimalFormat` A formatting object to get CSS compatible float strings.
`protected boolean` `hasChanged` Whether this value has changed since the last call to `hasChanged()`.
`protected AnimationTarget` `target` The target of the animation.

Constructor Summary
`protected` `AnimatableValue(AnimationTarget target)` Creates a new AnimatableValue.

Method Summary
`abstract boolean` `canPace()` Returns whether two values of this type can have their distance computed, as needed by paced animation.
`abstract float` `distanceTo(AnimatableValue other)` Returns the absolute distance between this value and the specified other value.
`static java.lang.String` `formatNumber(float f)` Returns a CSS compatible string version of the specified float.
`java.lang.String` `getCssText()` Returns the CSS text representation of the value.
`abstract AnimatableValue` `getZeroValue()` Returns a zero value of this AnimatableValue's type.
`boolean` `hasChanged()` Returns whether the value in this AnimatableValue has been modified.
`abstract AnimatableValue` `interpolate(AnimatableValue result, AnimatableValue to, float interpolation, AnimatableValue accumulation, int multiplier)` Performs interpolation to the given value.
`java.lang.String` `toString()` Returns a string representation of this object prefixed with its class name.
`java.lang.String` `toStringRep()` Returns a string representation of this object.

Field Detail

### decimalFormat

    protected static java.text.DecimalFormat decimalFormat

  A formatting object to get CSS compatible float strings.

### target

    protected AnimationTarget target

  The target of the animation.

### hasChanged

    protected boolean hasChanged

  Whether this value has changed since the last call to `hasChanged()`. This must be updated within `interpolate(org.apache.batik.anim.values.AnimatableValue, org.apache.batik.anim.values.AnimatableValue, float, org.apache.batik.anim.values.AnimatableValue, int)` in descendant classes.

Constructor Detail

### AnimatableValue

    protected AnimatableValue(AnimationTarget target)

  Creates a new AnimatableValue.

Method Detail

### formatNumber

    public static java.lang.String formatNumber(float f)

  Returns a CSS compatible string version of the specified float.

### interpolate

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

  Performs interpolation to the given value.

  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

### canPace

    public abstract boolean canPace()

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

### distanceTo

    public abstract float distanceTo(AnimatableValue other)

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

### getZeroValue

    public abstract AnimatableValue getZeroValue()

  Returns a zero value of this AnimatableValue's type.

### getCssText

    public java.lang.String getCssText()

  Returns the CSS text representation of the value.

### hasChanged

    public boolean hasChanged()

  Returns whether the value in this AnimatableValue has been modified.

### toStringRep

    public java.lang.String toStringRep()

  Returns a string representation of this object. This should be overridden in classes that do not have a CSS representation.

### toString

    public java.lang.String toString()

  Returns a string representation of this object prefixed with its class name.

  Overrides:
    `toString` in class `java.lang.Object`
