Méthodes publiques

Méthode Description
Clone ( ) : object

Abstract Clone() member function
decode ( byte buffer, int offset ) : int

Decodes the ASN.1 buffer and sets the values in the AsnType object.
encode ( MutableByte buffer ) : void

Encodes the data object in the specified buffer

Private Methods

Méthode Description
BuildHeader ( MutableByte mb, byte asnType, int asnLength ) : void

Build ASN.1 header in the MutableByte array.

Header is the TL part of the TLV (type, length, value) BER encoded data representation. Each value is encoded as a Type byte, length of the data field and the actual, encoded data. This method will encode the type and length fields.

BuildLength ( MutableByte mb, int asnLength ) : void

Append BER encoded length to the MutableByte
ParseHeader ( byte mb, int &offset, int &length ) : byte

Parse ASN.1 header.
ParseLength ( byte mb, int &offset ) : int

MutableByte version of ParseLength. Retrieve BER encoded length from a byte array at supplied offset
