New Revision: 36705

Modified:
   incubator/directory/snickers/branches/encoder-redesign/ber-codec/src/java/org/apache/snickers/ber/DeterminateLengthVisitor.java
Log:
Completed the visit method of this determinate length visitor which converts 
tlv trees with indeterminate length nodes into definate length tuples be 
decscending the tree in postfix order (depth first) to compute the child lengths
then finally the lengths of parents and ancestors in an indeterminate length 
tree.
