IntEvaluator

public class IntEvaluator
extends Object implements TypeEvaluator<Integer>

java.lang.Object
↳	android.animation.IntEvaluator

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

Summary

Public constructors
`IntEvaluator()`

Public methods
`Integer`	`evaluate(float fraction, Integer startValue, Integer endValue)` This function returns the result of linearly interpolating the start and end 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 obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Integer evaluate (float fraction, 
                Integer startValue, 
                Integer endValue)

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

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