Constructor Detail

AbstractElasticMotion

public AbstractElasticMotion(int start,
                             int stop,
                             long maxDuration)

Creates an elastic motion for a move from start to stop.

Parameters:

start - the start value.

stop - the stop value.

maxDuration - the maximum duration of the motion.

Method Detail

easeIn

protected int easeIn(long currentTime)

Gets the elastic ease in value for the given time.

Parameters:

currentTime - the elapsed time.

Returns:

the value for the given time.

easeOut

protected int easeOut(long currentTime)

Gets the elastic ease out value for the given time.

Parameters:

currentTime - the elapsed time.

Returns:

the value for the given time.

isFinished

protected boolean isFinished(int value)

Description copied from class: AbstractMotion

Checks whether the motion is finished or not, considering the given value.

By default, the motion is finished if the value reach (or exceed) the stop value.

Overrides:

isFinished in class AbstractMotion

Parameters:

value - the value to check with.

Returns:

true if the motion is finished, false otherwise.
