* crost.cpp
*
* Copyright (c) 1995 by DataBeam Corporation, Lexington, KY
*
* Abstract:
* This is the implementation file for the Conference Roster Class.
* Instances of this class represent a single Conference Roster's
* information base. It encapsulates all the functionality required to
* maintain the information base which includes the ability to add new
* roster records, delete records and update records. It has the ability
* to convert its internal information base into a list of conference
* records that can be used in a GCC_ROSTER_UPDATE_INDICATION callback.
* It is also responsible for converting its internal information base
* into Conference Roster Update PDUs. Basically, this class is
* responsible for all operations that require direct access to the
* records contained in a Conference Roster.
*
* The Conference Roster class incorporates Rogue Wave list to hold the
* roster record information. Using iterators throughout the class makes
* it easy to quickly convert the information contained in the list into
* either a PDU or into a list of record pointers (for roster update
* indications back to the node controller).
*
* A Conference Roster object has the ability to serialize its roster data
* into a single contiguous memory block when it is required to send a
* message to the application interface. This serialization process is
* managed externally by the CConfRosterMsg class through calls
* to LockConferenceRoster(), UnLockConferenceRoster() and
* GetConfRoster(). When a conference roster is to be serialized, a
* call is made to LockConferenceRoster() which causes the CConfRoster
* object to increment an internal lock count and returns the number of
* bytes required to hold the complete roster update. The Conference
* Roster is then serialized into memory through a call to
* GetConfRoster(). The CConfRoster is then unlocked to allow
* it to be deleted when the free flag gets set through the
* FreeConferenceRoster() function. In the current implementation of GCC,
* FreeConferenceRoster() is not used since the CConfRosterMsg
* maintains the data used to deliver the message.
*
* Private Instance Variables:
* m_RecordList2
* This is the rogue wave list used to hold the pointers to all of the
* rogue wave records.
* m_nInstanceNumber
* This instance variable maintains an up to date instance #
* corresponding to the current conference roster.
* m_fNodesAdded
* Flag indicating if any node records have been added to the
* conference roster since the last reset.
* m_fNodesRemoved
* Flag indicating if any node records have been removed from the
* conference roster since the last reset.
* m_fRosterChanged
* Flag indicating if the roster has changed since the last reset.
* m_uidTopProvider
* The node id of the top provider in the conference.
* m_uidSuperiorNode
* This is the node id of this nodes superior node. For the top
* provider this is zero.
* m_cbDataMemorySize
* This is the number of bytes required to hold the data associated
* with a roster update message. This is calculated on a lock.
* m_NodeInformation
* Structure used to hold the roster update indication node information
* data in "PDU" form.
* m_fTopProvider
* Flag indicating if the node where this roster lives is the top
* provider.
* m_fLocalRoster
* Flag indicating if the roster data is associated with a local
* roster (maintaining intermediate node data) or global roster (
* (maintaining roster data for the whole conference).
* m_fMaintainPduBuffer
* Flag indicating if it is necessary for this roster object to
* maintain internal PDU data. Won't be necessary for global rosters
* at subordinate nodes.
* m_fPduFlushed
* Flag indicating if the PDU that currently exists has been flushed.
* m_pNodeRecordUpdateSet
* Pointer to internal PDU data.
*
* Caveats:
* None.
