Inheritance diagram for PASNObject:

List of all members.


Detailed Description

This class defines the common behviour of all ASN objects. It also contains several functions which are used for encoding common ASN primitives.

This class will never be instantiated directly. See the PASNInteger, PASNSequence, PASNString and PASNObjectID classes for examples of ASN objects that can be created.

Only descendants of this class can be put into the ASNSequence class.
