STANDARD TELECOM MODULE

       The  Standard Telecom module is an original implementation of various standards managed by
       the International Telecommunictaion Union (ITU). At  the  heart  of  this  module  is  the
       Abstract  Syntax  Notation  (ANS.1)  which  is widely used to model data records and store
       certificates.

STANDARD TELECOM REFERENCE

       AsnNode
       The AsnNode class is the base class used to represent the asn tree. The structure  of  the
       node  is  defined  in ITU-T X.690 recommendation. This implementation supports 64 bits tag
       number with natural machine  length  encoding.  The  Canonical  Encoding  Rule  (CER)  and
       Distinguished  Encoding  Rule (DER) are defined by the class. Since ASN.1 provides several
       encoding schemes, the class is designed to be as generic as possible but does not provides
       the  mechanism  for  changing  from one representation to another although it is perfectly
       valid to read a DER representation and write it in the CER form.

       Methods

              write -> none (none|OutputStream|Buffer)
              The write method write the asn node contents as well  as  the  child  nodes  to  an
              output  stream  argument  or a buffer. Without argument, the node is written to the
              interpreter output stream. With one argument, the node is written to the  specified
              stream or buffer.

       AsnEoc
       The  AsnEoc  class  is  is  the  asn  object  class that encodes the eoc or end-of-content
       primitive. This primitive is  almost  never  used  but  its  encoding  is  used  with  the
       indefinite length encoding.

       Predicate

              asn-eoc-p

       Inheritance

              AsnNode

       Constructors

              AsnEoc (none)
              The AsnEoc constructor creates a default asn eoc node.
