void oofE_DuplicateRecord::extract (  std::ostream &  os  )  const [virtual]

Implements oofE_Base.

bool oofE_Table::originalTableStillInScope (   )  const [inline, inherited]

bool oofE_Table::receiveMsg (  OOFmsgT  msg, unsigned long  senderDefined )  [virtual, inherited]

The default receiveMsg behaviour is to delete yourself when the broadcaster closes. In many user subclasses oofSingleListener is a mixin and you have a class owned elsewhere, not self-deleting. Warning: If a subclass is not self-deleting it MUST override receiveMsg handling of the msg OOFmsg_BroadcasterClosing to prevent runtime error. However it is still important to set mListensTo=0 otherwise when you finally get around to deleting your oofSingleListener, it will try to update a deleted oofBroadcaster and cause a crash. Reimplemented from oofSingleListener.

void oofSingleListener::resumeListening (   )  [inherited]

void oofSingleListener::subscribeTo (  oofBroadcaster *   )  [virtual, inherited]

Reimplemented from oofReceiver.

void oofSingleListener::suspendListening (   )  [inherited]

dbTable * oofE_Table::table (   )  const [inline, inherited]

void oofSingleListener::unsubscribe (  oofBroadcaster *  from = 0  )  [virtual, inherited]

Reimplemented from oofReceiver.
