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

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 timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait()

Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

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

Added in API level 14
public 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 * (x1 - x0), 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.
