ErrorCode moab::RayIntersector::leaf ( EntityHandle node ) [virtual]

Process a leaf node during tree traversal.

Implements moab::OrientedBoxTreeTool::Op.

Definition at line 970 of file OrientedBoxTreeTool.cpp.

{
  boxes.insert(node);
  return MB_SUCCESS;
}

ErrorCode moab::RayIntersector::visit	(	EntityHandle	node,
		int	depth,
		bool &	descend
	)		`[virtual]`

Visit a node in the tree during a traversal.

This method is called for each node in the tree visited during a pre-order traversal.

Parameters:

node	The EntityHandle for the entity set for the tree node.
depth	The current depth in the tree.
descend	Output: if false, traversal will skip children of the current node, or if the current node is a leaf, the 'leaf' method will not be called.

Implements moab::OrientedBoxTreeTool::Op.
