com.objsys.asn1j.runtime.Asn1Context

public class Asn1Context
extends java.lang.Object

This class is a holder for things which are to be contained in an encoder or decoder. Since we have multiple base classes for encoders/decoders (Asn1MessageBuffer and Asn1OutputStream), this class provides a single container for all of those things which would otherwise be contained in the various base classes. This class also provides a location for some convenience methods related to the contained objects (e.g. getCurrentElement). Thread-safety: a given instance of this class should be accessed by a single thread.
