Interface AnimatingTree<P extends NodeProperties>

All Superinterfaces:

DrawingTree<P>, Tree<P>

All Known Implementing Classes:

GrowingTreeHead, GrowingTreeNode, MovingBSTTree

public interface AnimatingTree<P extends NodeProperties>
extends DrawingTree<P>

The AnimatingTree interface extends DrawingTree because all AnimatingTrees must be drawable.

The interface simply inforces the defining of numerous methods which allow for the animating of the Tree onto a given Graphics2D. The interface also defines many mutator and accesor methods for information concerning the animating of the AnimatingTree

Returns:

true if the node is currently animating.

addAnimator

void addAnimator(Animation a)

Adds an animation to the current node. This method does not add the node to listen for AnimationEvents. That must be performed by the user.

Parameters:
