Interface SessionDescription

All Superinterfaces:

Cloneable, Serializable

All Known Implementing Classes:

SessionDescriptionImpl

public interface SessionDescription
extends Serializable, Cloneable

A SessionDescription represents the data defined by the Session Description Protocol (see IETF RFC 2327) and holds information about the originitor of a session, the media types that a client can support and the host and port on which the client will listen for that media. The SessionDescription also holds timing information for the session (e.g. start, end, repeat, time zone) and bandwidth supported for the session. Please refer to IETF RFC 2327 for a description of SDP.
