Subject svn commit: r191596 - /directory/sandbox/trunk/asn1-new-codec/src/java/org/apache/asn1/ber/tlv/TLV.java
Date Tue, 21 Jun 2005 00:34:46 GMT
Author: elecharny

New Revision: 191596

URL: http://svn.apache.org/viewcvs?rev=191596&view=rev
Log:
Added a link to the parent TLV, and added a member to store the current TLV length. This member
is
used while decoding a PDU.
