CosNotifyChannelAdmin_EventChannelFactory (3erl)

To get access to the record definitions for the structures use:

-include_lib("cosNotification/include/*.hrl").

create_channel(ChannelFactory, InitialQoS, InitialAdmin) -> Return

Types:

ChannelFactory = #objref

InitialQoS = CosNotification::QoSProperties

InitialAdmin = CosNotification::AdminProperties

Return = {EventChannel, ChannelID}

EventChannel = #objref

ChannelID = long()

This operation creates a new event channel. Along with the channel reference an id is returned which can be used when invoking other operations exported by this module. The Quality of Service argument supplied will be inherited by objects created by the channel. For more information about QoS settings see the User's Guide.

If no QoS- and/or Admin-properties are supplied (i.e. empty list), the default settings will be used. For more information, see the User's Guide.

get_all_channels(ChannelFactory) -> ChannelIDSeq

Types:

ChannelFactory = #objref

ChannelIDSeq = [long()]

This operation returns a id sequence of all channel's created by this ChannelFactory.

get_event_channel(ChannelFactory, ChannelID) -> Return

Types:

ChannelFactory = #objref

ChannelID = long()

Retrurn = EventChannel | {'EXCEPTION', #'CosNotifyChannelAdmin_ChannelNotFound'{}}

EventChannel = #objref

This operation returns the EventChannel associated with the given id. If no channel is associated with the id, i.e., never existed or have been terminated, an exception is raised.
