SoLightweightPath Class Reference

A SoLightweightPath is a light-weight version of an SoTempPath, intended to be used just to keep track of the current path during traversal. More...

Public Member Functions
	SoLightweightPath (int approxLength)
	Constructor given approximate number of nodes in chain.
void	setHead (SoNode *node)
	Sets head node (first node in chain) Resulting path has only one node.
void	append (int childIndex)
	Adds node specified by childindex to end of chain.
void	push (int childIndex)
	Allows path to be treated as a stack: push a node at the end of the chain and pop the last node off.
void	push ()
void	pop ()
void	setTail (int childIndex)
SoNode *	getTail ()
SoNode *	getHead () const
	Returns the first node in a path chain.
SoNode *	getNode (int i) const
	Returns pointer to ith node in chain.
int	getFullLength () const
	Returns full length of path chain (number of nodes) note that public/private distinction is ignored.
void	truncate (int start)
	Removes all nodes from indexed node on.
void	makeTempPath (SoTempPath *tmpPath) const
	fills in nodes for a TempPath that is represented by this SoLightweightPath.

Detailed Description

Eventually it is intended to replace SoTempPath (when appropriate modifications are made to SoDraggers). Unlike SoPath, it keeps only a chain of childIndices and a headnode. The methods implemented are only those needed for traversal.
