Class BidirectionalTypeConverter<T,V>

java.lang.Object

icyllis.modernui.animation.BidirectionalTypeConverter<T,V>

All Implemented Interfaces:

TypeConverter<T,V>

public abstract class BidirectionalTypeConverter<T,V>
extends Object
implements TypeConverter<T,V>

Abstract base class used convert type T to another type V and back again. This is necessary when the value types of in animation are different from the property type. BidiTypeConverter is needed when only the final value for the animation is supplied to animators.

Method Details

convertBack

public abstract T convertBack(V value)

Does a conversion from the target type back to the source type. The subclass must implement this when a TypeConverter is used in animations and current values will need to be read for an animation.

Parameters:

value - The Object to convert.

Returns:

A value of type T, converted from value.

invert

public final BidirectionalTypeConverter<V,T> invert()

Returns the inverse of this converter, where the from and to classes are reversed. The inverted converter uses this convert to call convertBack(Object) for TypeConverter.convert(Object) calls and TypeConverter.convert(Object) for convertBack(Object) calls.

Returns:

The inverse of this converter, where the from and to classes are reversed.
