                              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

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
