All Implemented Interfaces:

Visitor, javax.swing.tree.TreeModel

Direct Known Subclasses:

Tree

public abstract class SceneTreeWithShader

Method Detail

getCurrentInterior

protected Interior getCurrentInterior()

getCurrentShader

protected Shader getCurrentShader()

init

protected void init(SceneTree.Leaf leaf)

Description copied from class: SceneTree

This method has to be invoked whenever a new SceneTree.Leaf is created as a leaf of this tree. The tree may perform some initialization tasks on the leaf.

Overrides:

init in class SceneTree

Parameters:

leaf - a newly created Leaf to be initialized

resolveShader

protected Shader resolveShader(Shader shader)

visitLeave

public boolean visitLeave(java.lang.Object o,
                          Path path,
                          boolean node)

Description copied from interface: Visitor

Informs this visitor that a node or an edge has been processed completely. The value o is the return value of the corresponding invocation of Visitor.visitEnter(de.grogra.graph.Path, boolean). In case of a node and if this invocation returns false, no further edges of the current level of hierarchy will be passed to this visitor, i.e., the visitLeave methods for the enclosing edge and node will be invoked immediately. Likewise, in case of an edge and a return value false, no further instantiations or edges of the current level of hierarchy will be passed to this visitor, i.e., the visitLeave method for the enclosing node will be invoked immediately.

Specified by:

visitLeave in interface Visitor

Overrides:

visitLeave in class SceneTree

Parameters:

o - returned value of visitEnter

path - current path to node

node - do we leave a node or an edge?

Returns:

true iff processing of current level shall be continued
