Detailed Description

ProxyPushConsumer.

Implement the RtecEventChannelAdmin::ProxyPushConsumer interface, remember that this class is used to communicate with a PushSupplier, so, in effect, this is the ambassador for a supplier inside the event channel.

Memory Management

It makes a copy of the SupplierQOS and the supplier object reference. It uses bind/unbind to control the lifetime of the Supplier_Filter object. The object commits suicide when disconnect_push_consumer() is called.

Locking

No provisions for locking, access must be serialized externally.
