svn commit: r704758 - /xerces/java/trunk/samples/ui/TreeView.java

[mr...@apache.org]

Author: mrglavas
Date: Tue Oct 14 18:24:22 2008
New Revision: 704758

URL: http://svn.apache.org/viewvc?rev=704758&view=rev
Log:
Minor performance improvement. Iterate over the entries in the map instead 
of the keys. This avoids a redundant table lookup for each value.
