Examples of codec.asn1.ASN1SequenceOf

org.apache.harmony.security.asn1.ASN1SequenceOf
Represents an ASN.1 SEQUENCE OF type as specified in ITU-T Recommendation X.680. The SequenceOf and SetOf types do not have default constructors in contrast to all the other ASN1Types. The reason is that these types are never created directly on decoding ASN.1 structures. The decoding process always decodes Sequence and Set types because creating the appropriate SequenceOf or SetOf type requires explicit knowledge of the syntactic structure definition. On the other hand, if an explicit structure is given for decoding then the SequenceOf and SetOf types are decoded properly (because they do not have to be created and hence the decoder need not know the component type).
Constraints are checked only after decoding by a call to method {@link #decode decode}. @author Volker Roth @author Stefan Endler @version "$Id: ASN1SequenceOf.java,v 1.3 2007/08/11 18:21:50 sendler Exp $"
