void CosEventComm::PullSupplier::disconnect_pull_supplier (    )

The peer has disconnected from the pull-style supplier. The disconnect_pull_supplier operation indicates that the peer has disconnected, for example, because it has been destroyed. The application can safe release all resource attached to this supplier and destroy it, the peer should not make any attempts to pull more data after this request.

any CosEventComm::PullSupplier::pull (    )  raises (Disconnected)

Pull (blocking) one event from the supplier. The pull operation should block until the next event becomes available. Returns: The next event Exceptions: CosEventComm::Disconnected  if the object considers itself no longer connected to its peer.

any CosEventComm::PullSupplier::try_pull (  out boolean    has_event )  raises (Disconnected)

Pull (non-blocking) one event from the supplier. The try_pull operation does not block: if the event data is available, it returns the event data and sets the has_event parameter to true; if the event is not available, it sets the has_event parameter to false and the event data is returned as long with an undefined value. Parameters: has_event  Set to TRUE if there was another event available, FALSE otherwise. Returns: The next event if one was available, an any containing a 'long' with an undefined value otherwise. Exceptions: CosEventComm::Disconnected  if the object considers itself no longer connected to its peer.
