Examples of codec.asn1.ASN1Set

org.bouncycastle.asn1.ASN1Set
Represents an ASN.1 SET type as specified in ITU-T Recommendation X.680.
This implementation does not sort the elements according to their encodings as required (in principle) by the standard. Upon decoding, all decoded elements are kept in the order they appeared in the encoded stream. @author Volker Roth @author Stefan Endler @version "$Id: ASN1Set.java,v 1.3 2007/08/11 18:21:50 sendler Exp $"
