CosEventChannelAdmin_EventChannel(3erl) 		     Erlang Module Definition			   CosEventChannelAdmin_EventChannel(3erl)

NAME

       CosEventChannelAdmin_EventChannel  -  This  module  implements an Event Channel interface, which plays the role of a  mediator between con-
       sumers and suppliers.

DESCRIPTION

       An event channel is an object that allows multiple suppliers to communicate with multiple consumers in  a  highly  decoupled,  asynchronous
       manner.	The event channel is built up incrementally. When an event channel is created no suppliers or consumers are connected to it. Event
       Channel can implement group communication by serving as a replicator, broadcaster, or multicaster that forward events from one or more sup-
       pliers to multiple consumers.

       It  is  up to the user to decide when an event channel is created and how references to the event channel are obtained. By representing the
       event channel as an object, it has all of the properties that apply to objects. One way to manage an event channel is to register it  in  a
       naming context, or export it through an operation on an object.

       To get access to all definitions 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

       for_consumers(Object) -> Return

	      Types  Object = #objref
		     Return = #objref

	      This operation returns a ConsumerAdmin object reference. If ConsumerAdmin object does not exist already it creates one.

       for_suppliers(Object) -> Return

	      Types  Object = #objref
		     Return = #objref

	      This operation returns a SupplierAdmin object reference. If SupplierAdmin object does not exist already it creates one.

       destroy(Object) -> Return

	      Types  Object = #objref
		     Return = #objref

NAME

       CosNotifyFilter_FilterAdmin - This module implements the OMG CosNotifyFilter::FilterAdmin interface.

DESCRIPTION

       To get access to the record definitions for the structures use:
       -include_lib("cosNotification/include/*.hrl").

       All objects, which inherit this interface, export functions described in this module.

EXPORTS

       add_filter(Object, Filter) -> FilterID

	      Types  Object = #objref
		     Filter = #objref
		     FilterID = long()

	      This  operation  connects  a  new Filter to the target object. This Filter will, together with other associated Filters , be used to
	      select events to forward. A unique Id is returned and should be used if we no longer want to consult the given Filter .

       remove_filter(Object, FilterID) -> ok

	      Types  Object = #objref
		     FilterID = long()

	      If a certain Filter no longer should be associated with the target object this operation must be used.  Events  will  no	longer	be
	      tested against the Filter associated with the given Id.

       get_filter(Object, FilterID) -> Reply

	      Types  Object = #objref
		     FilterID = long()
		     Reply = Filter | {'EXCEPTION', #'CosNotifyFilter_FilterNotFound'{}}
		     Filter = #objref

	      If the target object is associated with a Filter matching the given Id the reference will be returned. If no such Filter is known by
	      the target object an exception is raised.

       get_all_filters(Object) -> FilterIDSeq

	      Types  Object = #objref
		     FilterIDSeq = [FilterID]
		     FilterID = long()

	      Id's for all Filter objects associated with the target object is returned by this operation.

       remove_all_filters(Object) -> ok

	      Types  Object = #objref

	      If we want to remove all Filters associated with the target object we can use this function.
