IntArrayEvaluator

Class Overview

This evaluator can be used to perform type interpolation between int[] values. Each index into the array is treated as a separate value to interpolate. For example, evaluating {100, 200} and {300, 400} will interpolate the value at the first index between 100 and 300 and the value at the second index value between 200 and 400.

Summary

Public Constructors
	IntArrayEvaluator() Create an IntArrayEvaluator that does not reuse the animated value.
	IntArrayEvaluator(int[] reuseArray) Create an IntArrayEvaluator that reuses `reuseArray` for every evaluate() call.

Public Constructors

IntArrayEvaluator()

Create an IntArrayEvaluator that does not reuse the animated value.

IntArrayEvaluator(int[] reuseArray)

Create an IntArrayEvaluator that reuses reuseArray for every evaluate() call.

Public Methods
int[]	evaluate(float fraction, int[] startValue, int[] endValue) Interpolates the value at each index by the fraction.

Public Methods

int[]

evaluate(float fraction, int[] startValue, int[] endValue)

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.

Public Constructors

public IntArrayEvaluator ()

Added in API level 21

Create an IntArrayEvaluator that does not reuse the animated value. Care must be taken when using this option because on every evaluation a new int[] will be allocated.

public IntArrayEvaluator (int[] reuseArray)

Added in API level 21

Create an IntArrayEvaluator that reuses reuseArray for every evaluate() call. Caution must be taken to ensure that the value returned from getAnimatedValue() is not cached, modified, or used across threads. The value will be modified on each evaluate() call.

Parameters

reuseArray	The array to modify and return from `evaluate`.

Public Methods

public int[] evaluate (float fraction, int[] startValue, int[] endValue)

Added in API level 21

Interpolates the value at each index by the fraction. If IntArrayEvaluator(int[]) was used to construct this object, reuseArray will be returned, otherwise a new int[] will be returned.

Parameters

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

Returns

An int[] where each element is an interpolation between the same index in startValue and endValue.
