PointFEvaluator

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

Summary

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

Public Constructors

PointFEvaluator()

Construct a PointFEvaluator that returns a new PointF on every evaluate call.

PointFEvaluator(PointF reuse)

Constructs a PointFEvaluator that modifies and returns reuse in evaluate(float, android.graphics.PointF, android.graphics.PointF) calls.

Public Methods
PointF	evaluate(float fraction, PointF startValue, PointF endValue) This function returns the result of linearly interpolating the start and end PointF 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 PointFEvaluator ()

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

public PointFEvaluator (PointF reuse)

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

Parameters

reuse	A PointF to be modified and returned by evaluate.

Public Methods

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

This function returns the result of linearly interpolating the start and end PointF 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 PointF objects (x, y).

If PointFEvaluator(android.graphics.PointF) was used to construct this PointFEvaluator, the object returned will be the reuse passed into the constructor.

Parameters

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

Returns

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