virtual ErrorCode TriStats::visit | ( | EntityHandle | node, |
int | depth, | ||
bool & | descend | ||
) | [inline, 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.
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. |
