◆ leaf()

ErrorCode moab::TreeLayoutPrinter::leaf ( EntityHandle  node)
virtual

Process a leaf node during tree traversal.

Implements moab::OrientedBoxTreeTool::Op.

Definition at line 1469 of file OrientedBoxTreeTool.cpp.

1470 {
1471  return MB_SUCCESS;
1472 }

References MB_SUCCESS.

◆ visit()

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
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.
