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 Float evaluate (float fraction, Number startValue, Number endValue)

Added in API level 14

This function returns the result of linearly interpolating the start and end values, with fraction representing the proportion between the start and end values. The calculation is a simple parametric calculation: result = x0 + t * (v1 - v0) , where x0 is startValue , x1 is endValue , and t is fraction .

Parameters

fraction	The fraction from the starting to the ending values
startValue	The start value; should be of type `float` or `Float`
endValue	The end value; should be of type `float` or `Float`

Returns

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