Method Detail

stop

public void stop()

Description copied from class: BasicAnimator

Stops the Animator, hasNext will now return false

Specified by:

stop in interface Animator

Overrides:

stop in class BasicAnimator

setImpl

protected void setImpl(double interpolant)

Description copied from class: BasicAnimator

No-op intended to be overrided by deriving classes. Deriving classes are expected to implement the desired action of a set operation in this method.

Overrides:

setImpl in class BasicAnimator

Parameters:

interpolant - A value between 0 and 1.

updateTargetValues

protected void updateTargetValues()

valuesMeetCriteria

protected boolean valuesMeetCriteria(Position centerPos,
                                     double zoom)
