RectEvaluator

This evaluator can be used to perform type interpolation between Rect values.

Summary

Public Constructors
	RectEvaluator() Construct a RectEvaluator that returns a new Rect on every evaluate call.
	RectEvaluator(Rect reuseRect) Constructs a RectEvaluator that modifies and returns `reuseRect` in `evaluate(float, android.graphics.Rect, android.graphics.Rect)` calls.

Public Constructors

RectEvaluator()

Construct a RectEvaluator that returns a new Rect on every evaluate call.

RectEvaluator(Rect reuseRect)

Constructs a RectEvaluator that modifies and returns reuseRect in evaluate(float, android.graphics.Rect, android.graphics.Rect) calls.

Public Methods
Rect	evaluate(float fraction, Rect startValue, Rect endValue) This function returns the result of linearly interpolating the start and end Rect values, with `fraction` representing the proportion between the start and end values.

Inherited Methods

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.

From interface android.animation.TypeEvaluator

Public Constructors

public RectEvaluator ()

Added in API level 18

Construct a RectEvaluator that returns a new Rect on every evaluate call. To avoid creating an object for each evaluate call, RectEvaluator(android.graphics.Rect) should be used whenever possible.

public RectEvaluator (Rect reuseRect)

Constructs a RectEvaluator that modifies and returns reuseRect in evaluate(float, android.graphics.Rect, android.graphics.Rect) calls. The value returned from evaluate(float, android.graphics.Rect, android.graphics.Rect) should not be cached because it will change over time as the object is reused on each call.

Parameters

reuseRect	A Rect to be modified and returned by evaluate.

Public Methods

public Rect evaluate (float fraction, Rect startValue, Rect endValue)

Added in API level 18

This function returns the result of linearly interpolating the start and end Rect values, with fraction representing the proportion between the start and end values. The calculation is a simple parametric calculation on each of the separate components in the Rect objects (left, top, right, and bottom).

If RectEvaluator(android.graphics.Rect) was used to construct this RectEvaluator, the object returned will be the reuseRect passed into the constructor.

Parameters

fraction	The fraction from the starting to the ending values
startValue	The start Rect
endValue	The end Rect

Returns

A linear interpolation between the start and end values, given the fraction parameter.
