CosEventChannelAdmin_­ProxyPushSupplier

# 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.

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 ProxyPushSupplier interface can perform the following operations:

### EXPORTS

`connect_push_consumer(Object, PushConsumer) -> Return`

Types:

`Object = #objref`
`PushConsumer = #objref of PushConsumer type`
`Return = ok | {'EXCEPTION', E}`
`E = #'CosEventChannelAdmin_AlreadyConnected'{} | #'CosEventChannelAdmin_TypeError'{}`

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 `CosEventChannelAdmin_AlreadyConnected` exception is raised. Implementations of ProxyPushSuppliers may require additional interface functionality; if these requirements are not met the `CosEventChannelAdmin_TypeError` exception will be raised.

`disconnect_push_supplier(Object) -> Return`

Types:

`Object = #objref`
`Return = ok`

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.
