CosEventChannelAdmin_ProxyPullConsumer

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

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:

Functions

connect_pull_supplier(Object, PullSupplier) -> Return

  • 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

  • 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.
