CosEventChannelAdmin_ProxyPushSupplier
This module implements a ProxyPushSupplier interface which acts as a middleman between push consumer and the event channel.
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:
Functions
connect_push_consumer(Object, PushConsumer) -> Return
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
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.
