Java tree object

Posted on 2001-08-01
Last Modified: 2007-12-19
I'm after a class that will allow me to add objects in a tree form.  A bit like TreeMap but with tree walking/traversing methods.


Tree mytree = new Tree();
mytree.addRoot( rootObj );
mytree.putChild( obj1, rootObj );
mytree.putChild( obj2, rootObj );
mytree.putChild( obj3, obj1 );

Collection children = mytree.getChildren( obj1 );
//returns a collection containing just obj3

Iterator i = mytree.getTree( rootObj ).iterator();
while( i.hasNext() )
{ //=next in a tree walk
  //in this example gives the order as
  //rootObj, obj1, obj3, obj2

I'm just trying a DOM tree but it seems abit long winded for such a simple thing.

Thanks for your help,

Thanks for all your help.

I eventually wrote a tree implementation using collections since the j2ee server i was using would not shut down properly if I used awt or swing classes.
