/directory/asn1/trunk/codec/src/main/java/org/apache/asn1/codec/util/Asn1StringUtils.java
Author: elecharny
Date: Mon Dec 26 12:20:10 2005
New Revision: 359092

Log:
- Renamed StringUtils to Asn1StringUtils
- Removed all unused methods (they have moved to
ldap-common/StringTools )
Added:
directory/asn1/trunk/codec/src/main/java/org/apache/asn1/codec/util/Asn1StringUtils.java
- copied, changed from r359001, directory/asn1/trunk/codec/src/main/java/org/apache/asn1/codec/util/StringUtils.java
