[Treebase-guts] SF.net SVN: treebase:[413] trunk/treebase-core/src/main/java/org/cipres/ treebase/NamespacedGUID.java

[<rv...@us...>]

Revision: 413
          http://treebase.svn.sourceforge.net/treebase/?rev=413&view=rev
Author:   rvos
Date:     2010-01-12 17:03:22 +0000 (Tue, 12 Jan 2010)

Log Message:
-----------
Implemented getHashedIDString() method. This method returns a hashed (currently MD5) version of the namespaced GUID, which is to be used by the reviewer access control system as the "x-access-code" parameter. Also fixed the spelling of the mNamespacedGUID private variable's name.
