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:
nodeThe EntityHandle for the entity set for the tree node.
depthThe current depth in the tree.
descendOutput: 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.
