svn commit: r704535 -
/xerces/java/branches/xml-schema-1.1-dev/src/org/apache/xerces/dom/CoreDocumentImpl.java
Author: mrglavas
Date: Tue Oct 14 06:33:14 2008
New Revision: 704535
URL: http://svn.apache.org/viewvc?rev=704535&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.
