Just a thought, how about this:-
Node node = ..;
boolean hasChildren = false;
if ( node instanceof Branch ) {
Branch branch = (Branch) node;
hasChildren = branch.nodeCount() > 0;
}
The same thing could be done in one line of code (albeit a bit messy)
if ( node instanceof Branch && ((Branch) node).nodeCount() > 0 ) {
// I have children...
}
Would having the hasChildren() make your code much simpler?
