NAME
       itu - standard telecom module

STANDARD TELECOM MODULE
       The  Standard  Telecommodule  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 AsnNodeclass	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  en-
       coding  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.

       Predicate

	      asn-node-p

       Inheritance

	      Object

       Methods

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

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

       Predicate

	      asn-eoc-p

       Inheritance

	      AsnNode

       Constructors

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