Manual Reference Pages  -  COSEVENTCHANNELADMIN_PROXYPUSHCONSUMER (3)

NAME

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

CONTENTS

Description
Exports

DESCRIPTION

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 hrl files by using:
-include_lib("cosEvent/include/*.hrl").

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

EXPORTS

connect_push_supplier(Object, PushSupplier) -> Return

Types:

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 CosEventChannelAdmin_AlreadyConnected exception is raised.

disconnect_push_consumer(Object) -> Return

Types:

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

Types:

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 CosEventComm_Disconnected is raised.
