◆ visit()

ErrorCode moab::RayIntersectSets::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.
