ErrorCode moab::TreeLayoutPrinter::leaf

(

EntityHandle

node

)

[virtual]

Process a leaf node during tree traversal.

Implements moab::OrientedBoxTreeTool::Op.

Definition at line 1770 of file OrientedBoxTreeTool.cpp.

{ return MB_SUCCESS; }

ErrorCode moab::TreeLayoutPrinter::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.

  if ((unsigned)depth > path.size()) {

  else {
    path.resize( depth );
    if (depth)
      path.back() = false;
  }
