CosEventChannelAdmin_ProxyPushSupplier

MODULE

CosEventChannelAdmin_ProxyPushSupplier

MODULE SUMMARY

This module implements a ProxyPushSupplier interface which acts as a middleman between push consumer and the event channel.

DESCRIPTION

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

There are a number of exceptions that can be returned from functions in this interface.

• AlreadyConnected is defined as -record('AlreadyConnected', {}).
• CORBA standard BAD_PARAM is defined as -record('BAD_PARAM', {'OE_ID', minor, completion_status}).

The first exception is defined in the file event_service.hrl and the second one in the file corba.hrl.

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

EXPORTS

connect_push_consumer(Object, PushConsumer) -> Return

Types:
Object = #objref
PushConsumer = #objref of PushConsumer type
Return = void

This operation connects PushConsumer object to the ProxyPushSupplier object. If a nil object reference is passed CORBA standard BAD_PARAM exception is raised. If the ProxyPushSupplier is already connected to a PushConsumer, then the AlreadyConnected exception is raised.

disconnect_push_supplier(Object) -> Return

Types:
Object = #objref
Return = void

This operation disconnects proxy push supplier from the event channel and sends a notification about the loss of the connection to the push consumer attached to it.
