Subject svn commit: r422905 - /directory/branches/shared/optimization/asn1/src/main/java/org/apache/directory/shared/asn1/ber/Asn1Decoder.java
Date Mon, 17 Jul 2006 22:32:35 GMT
Author: elecharny
Date: Mon Jul 17 15:32:35 2006
New Revision: 422905

URL: http://svn.apache.org/viewvc?rev=422905&view=rev
Log:
- Created a static final boolean IS_DEBUG which is initialized with the 
logger when the class is loaded : this will be evaluated only once, so
we will avoid a lot of isDebugEnabled() calls.
