svn commit: r1225390 - /xalan/java/trunk/src/org/apache/xalan/xsltc/dom/SAXImpl.java

Author: mrglavas
Date: Wed Dec 28 23:29:18 2011
New Revision: 1225390

URL: http://svn.apache.org/viewvc?rev=1225390&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.
