Field Summary

static int	POST_ORDER Constant that tells about the order of graph traversal.
static int	PRE_ORDER Constant that tells about the order of graph traversal.

Method Summary

int	getOrder() Returns a constant that defines the order of graph traversal.
void	visit(Subgraph subgraph, int level) Callback invoked during traversal of graph-hierarchies.

Method Detail

getOrder

public int getOrder()

Returns a constant that defines the order of graph traversal. This constant can be either PRE_ORDER, which means that subgraphs are visited after the actual node is visited, or POST_ORDER, which means that subgraphs are visited before the actual node is visited.

Returns:

int the constant that defines the order of graph traversal

visit

public void visit(Subgraph subgraph,
                  int level)

Callback invoked during traversal of graph-hierarchies.

Parameters:

subgraph - the Subgraph that is currently being visited.

level - the depth of the recursion, which is measured from the beginning point of the recursion. This does not necessarily have to be the top-level-graph if the recursion was initiated from an already nested graph.
