svn commit: r704542 -
/xerces/java/trunk/src/org/apache/xerces/dom/CoreDocumentImpl.java
Author: mrglavas
Date: Tue Oct 14 06:58:47 2008
New Revision: 704542
URL: http://svn.apache.org/viewvc?rev=704542&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.
