visitEnterImpl

protected void visitEnterImpl(java.lang.Object object,
                              boolean asNode,
                              Path path)

Description copied from class: Visitor3D

This method has to be implemented by subclasses. It is invoked when object is entered.

Specified by:

visitEnterImpl in class Visitor3D

Parameters:

object - the object being entered

asNode - is object a node or an edge?

path - the path to object if object is a node, the path to the node where object points to if object is an edge

visitImpl

protected abstract void visitImpl(java.lang.Object object,
                                  boolean asNode,
                                  Shader s,
                                  Path path)

visitLeaveImpl

protected void visitLeaveImpl(java.lang.Object object,
                              boolean asNode,
                              Path path)

Description copied from class: Visitor3D

This method has to be implemented by subclasses. It is invoked when object is left.

Specified by:

visitLeaveImpl in class Visitor3D

Parameters:

object - the object being left

asNode - is object a node or an edge?

path - the path to object if object is a node, the path to the node where object points to if object is an edge
