Get whether a synchronization source is recorded in this membership controller. | |

Incoming RTP data packets control structure within the incoming packet queue class. More... | |
struct | SyncSourceLink |
Synchronization Source internal handler within the incoming packets queue. More... |
For now, this class implements only a hash table of members, but its design and relation with other classes is intented to support group membership sampling in case scalability problems arise.
MembershipBookkeeping::MembershipBookkeeping | ( | uint32 | initialSize = defaultMembersHashSize |
) | [protected] |
The initial size is a hint to allocate the resources needed in order to keep the members' identifiers and associated information.
Although ccRTP will reallocate resources when it becomes necessary, a good hint may save a lot of unpredictable time penalties.
initialSize | an estimation of how many participants the session will consist of. |
virtual MembershipBookkeeping::~MembershipBookkeeping | ( | ) | [inline, protected, virtual] |
Purges all RTPSource structures created during the session, as well as the hash table and the list of sources.

SyncSourceLink* MembershipBookkeeping::getLink | ( | const SyncSource & | source | ) | const [inline, protected] |
Reimplemented from SyncSourceHandler.
bool MembershipBookkeeping::isMine | ( | const SyncSource & | source | ) | const [inline, protected] |
Get whether a synchronization source is recorded in this membership controller.
bool MembershipBookkeeping::isRegistered | ( | uint32 | ssrc | ) | [protected] |
Returns whether there is already a synchronizacion source with "ssrc" SSRC identifier.
SyncSourceLink* MembershipBookkeeping::getSourceBySSRC | ( | uint32 | ssrc, | |
bool & | created | |||
) | [protected] |
Get the description of a source by its ssrc
identifier.
ssrc | SSRC identifier, in host order. | |
created | whether a new source has been created. |
ssrc
. bool MembershipBookkeeping::BYESource | ( | uint32 | ssrc | ) | [protected] |
Mark the source identified by ssrc
as having sent a BYE packet.
It is not deleted until a timeout expires, so that in case some packets from this source arrive a bit later the source is not inserted again in the table of known sources.
bool MembershipBookkeeping::removeSource | ( | uint32 | ssrc | ) | [protected] |
Remove the description of the source identified by ssrc
.
