Description

As discussed in ML, org.apache.commons.graph.visit.GraphVisitHandler methods that return boolean flags can be sometimes not so intuitive.

The proposal is replacing boolean flags return statements with an enumeration values ABORT, CONTINUE, SKIP to identify

• visit has to be immediately terminated
• visit can continue;
• current node children visit can be skipped.
