BidirectionalTypeConverter

Class Overview

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. BidirectionalTypeConverter is needed when only the final value for the animation is supplied to animators.

Inherited Methods

From class android.animation.TypeConverter

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Methods

public abstract T convertBack (V value)

Added in API level 21

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.

public BidirectionalTypeConverter<V, T> invert ()

Added in API level 21

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 convert(Object) calls and convert(Object) for convertBack(Object) calls.

Returns

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