Member Function Documentation

ACE_INLINE int OpenDDS::DCPS::PacketRemoveVisitor::status

(

)

const

Accessor for the status. Called after this visitor object has been passed to BasicQueue<T>::accept_remove_visitor(). status == 1 means the sample was found and removed. status == 0 means the sample was not found (thus not removed) status == -1 means a fatal error was encountered.

int OpenDDS::DCPS::PacketRemoveVisitor::visit_element_ref

(

TransportQueueElement *&

element

)

[virtual]

The BasicQueue<T>::accept_remove_visitor() method will call this visit_element() method for each element in the queue.
