Detailed Description

Default servant for ProxyPushConsumer objects.

All objects are implemented by a single instance of this servant class. This enables us to deal statelessly with anonymous connections (where connect_push_supplier() is called with a NIL callback reference).

Member Function Documentation

void OmniEvents::ProxyPushConsumer_i::connect_push_supplier ( CosEventComm::PushSupplier_ptr pushSupplier )

If pushSupplier is provided, then it is stored in _connections.

Otherwise this method does nothing.

CosEventChannelAdmin::ProxyPushConsumer_ptr OmniEvents::ProxyPushConsumer_i::createObject ( )

Constructs a new object.

This method is almost completely stateless. It makes a new objectId, and returns it to the caller. But, only when it's USED the first time (connect_push_consumer) do we store it in _connections. (Note, The POA doesn't store objects either.)
