Class LinearInterpolator

- All Implemented Interfaces:
Interpolator
public final class LinearInterpolator extends java.lang.Object implements Interpolator
This class implements the Interpolator interface by providing a simple interpolate function that simply returns the value that it was given. The net effect is that callers will end up calculating values linearly during intervals.Because there is no variation to this class, it is a singleton and is referenced by using the
getInstance()
static method.

interpolate
public float interpolate(float fraction)
This method always returns the value it was given, which will cause callers to calculate a linear interpolation between boundary values.- Specified by:
interpolate
in interfaceInterpolator
- Parameters:
fraction
- a value between 0 and 1, representing the elapsed fraction of a time interval (either an entire animation cycle or an interval between two KeyTimes, depending on where this Interpolator has been set)- Returns:
- the same value passed in as
fraction
