NAME

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

DESCRIPTION

11       An  event channel is an object that allows multiple suppliers to commu‐
12       nicate with multiple consumers in a highly decoupled, asynchronous man‐
13       ner. The event channel is built up incrementally. When an event channel
14       is created no suppliers or consumers are connected to it. Event Channel
15       can  implement  group  communication by serving as a replicator, broad‐
16       caster, or multicaster that forward events from one or  more  suppliers
17       to multiple consumers.
18
19       It is up to the user to decide when an event channel is created and how
20       references to the event channel are obtained. By representing the event
21       channel  as  an  object,  it  has  all  of the properties that apply to
22       objects. One way to manage an event channel is to register it in a nam‐
23       ing context, or export it through an operation on an object.
24
25       To get access to all definitions include necessary hrl files by using:
26       -include_lib("cosEvent/include/*.hrl").
27
28       Any  object that possesses an object reference that supports the Proxy‐
29       PullConsumer interface can perform the following operations:

EXPORTS

32       for_consumers(Object) -> Return
33
34              Types:
35
36                 Object = #objref
37                 Return = #objref
38
39              This operation returns a ConsumerAdmin object reference. If Con‐
40              sumerAdmin object does not exist already it creates one.
41
42       for_suppliers(Object) -> Return
43
44              Types:
45
46                 Object = #objref
47                 Return = #objref
48
49              This operation returns a SupplierAdmin object reference. If Sup‐
50              plierAdmin object does not exist already it creates one.
51
52       destroy(Object) -> Return
53
54              Types:
55
56                 Object = #objref
57                 Return = #objref
