# CosEventChannelAdmin\_ProxyPullConsumer(3erl)

This module implements a ProxyPullConsumer interface which acts as a middleman between pull supplier and the event channel.

## NAME

CosEventChannelAdmin\_ProxyPullConsumer - This module implements a ProxyPullConsumer interface which acts as a middleman between pull supplier and the event channel.

## DESCRIPTION

The ProxyPullConsumer interface defines the second step for connecting pull 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 *hrl* files by using:\
 *-include\_lib("cosEvent/include/\*.hrl").*

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

## EXPORTS

**connect\_pull\_supplier(Object, PullSupplier) -\> Return**\

Types:

Object = #objref\
 PullSupplier = #objref of PullSupplier type\
 Return = ok \| {'EXCEPTION', E}\
 E = #'CosEventChannelAdmin\_AlreadyConnected'{} \| #'CosEventChannelAdmin\_TypeError'{}\

This operation connects PullSupplier object to the ProxyPullConsumer object. If a nil object reference is passed CORBA standard *BAD\_PARAM* exception is raised. If the ProxyPullConsumer is already connected to a PullSupplier, then the *CosEventChannelAdmin\_AlreadyConnected* exception is raised. Implementations of ProxyPullConsumers may require additional interface functionality; if these requirements are not met the *CosEventChannelAdmin\_TypeError* exception will be raised.

**disconnect\_pull\_consumer(Object) -\> Return**\

Types:

Object = #objref\
 Return = ok\

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