CosEventChannelAdmin(3erl)	     Erlang Module Definition	       CosEventChannelAdmin(3erl)

       CosEventChannelAdmin  - The CosEventChannelAdmin defines a set if event service interfaces
       that  enables decoupled asynchronous communication between objects and implements  generic
       (untyped) version of the OMG COSS standard event service.

       The  event service defines two roles for objects: the supplier role and the consumer role.
       Suppliers supply event data to the event channel and consumers receive event data from the
       channel. Suppliers do not need to know the identity of the consumers, and vice versa. Con-
       sumers and suppliers are connected to the event channel via proxies, which are managed  by
       ConsumerAdmin and SupplierAdmin objects.

       There are four general models of communication. These are:

	 * The	canonical  push model. It allows the suppliers of events to initiate the transfer
	   of event data to consumers. Event channels play the role of Notifier . Active  suppli-
	   ers	use  event  channel  to  push data to passive consumers registered with the event

	 * The canonical pull model. It allows consumers to request events from suppliers.  Event
	   channels  play  the	role of Procure since they procure events on behalf of consumers.
	   Active consumers can explicitly pull data from passive suppliers via the  event  chan-

	 * The	hybrid push/pull model. It allows consumers request events queued at a channel by
	   suppliers. Event channels play the role of Queue . Active  consumers  explicitly  pull
	   data deposited by active suppliers via the event channels.

	 * The	hybrid	pull/push  model. It allows the channel to pull events from suppliers and
	   push them to consumers. Event channels play the role of  Intelligent  agent	.  Active
	   event channels can pull data from passive suppliers to push it to passive consumers.

       To get access to all definitions, e.g., exceptions, include necessary hrl files by using:

       There are seven different interfaces supported in the service:

	 * ProxyPushConsumer

	 * ProxyPullSupplier

	 * ProxyPullConsumer

	 * ProxyPushSupplier

	 * ConsumerAdmin

	 * SupplierAdmin

	 * EventChannel
