Interface TreeIterator

All Superinterfaces:

java.util.Iterator

All Known Implementing Classes:

TreeIteratorABDC, TreeIteratorACBD, TreeIteratorDBCA, TreeIteratorLeaves

public interface TreeIterator

extends java.util.Iterator

This interface specifies the TreeIterator. The implementation names for this interface have the name TreeIteratorXXXX where the XXXX letters represent the order of the returned nodes and each X is A, B, C or D.
If you consider a tree with the form, and the returned order is A, B, C and D, the iterator will be called TreeIteratorABCD.

     A
    / \
   B   C
  /
 D
 

 Example: 
 DefaultMutableTreeNode a = new DefaultMutableTreeNode("A");
 DefaultMutableTreeNode b = new DefaultMutableTreeNode("B");
 DefaultMutableTreeNode c = new DefaultMutableTreeNode("C");
 DefaultMutableTreeNode d = new DefaultMutableTreeNode("D");
 
 a.add(b);
 a.add(c);
 b.add(d);
 
 TreeIterator i = new TreeIteratorABDC(a);
 
 while(i.hasNext())
   System.err.println(i.nextNode());
 The output will be 
 A
 B
 D
 C
