CosEventChannelAdmin_ProxyPushConsumer This module implements a ProxyPushConsumer interface which acts as a middleman between push supplier and the event channel.

The ProxyPushConsumer interface defines the second step for connecting push suppliers to the event channel. A proxy consumer is similar to a normal consumer, but includes an additional method for connecting a supplier to the proxy consumer.

To get access to all definitions, e.g., exceptions, include necessary files by using:

Any object that possesses an object reference that supports the ProxyPushConsumer interface can perform the following operations:

 connect_push_supplier(Object, PushSupplier) -> Return Connect the push supplier to the proxy push consumer Object = #objref PushSupplier = #objref of PushSupplier type Return = ok | {'EXCEPTION', #'CosEventChannelAdmin_AlreadyConnected'{}}

This operation connects PushSupplier object to the ProxyPushConsumer object. A nil object reference can be passed to this operation. If so a channel cannot invoke the disconnect_push_supplier operation on the supplier; the supplier may be disconnected from the channel without being informed. If the ProxyPushConsumer is already connected to a PushSupplier, then the exception is raised.

 disconnect_push_consumer(Object) -> Return Disconnect the ProxyPushConsumer object from the event channel. Object = #objref Return = ok

This operation disconnects proxy push consumer from the event channel. Sends a notification about the loss of the connection to the push supplier attached to it, unless nil object reference was passed at the connection time.

 push(Object, Data) -> Return Communicate event data to the consumers. Object = #objref Data = any Return = ok | {'EXCEPTION', #'CosEventComm_Disconnected'{}}

This operation sends event data to all connected consumers via the event channel. If the event communication has already been disconnected, the is raised.
