MODULE

cosNotificationApp

MODULE SUMMARY

The main module of the cosNotification application.

DESCRIPTION

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

This module contains the functions for starting and stopping the application.

EXPORTS

install() -> Return

Types:
Return = ok | {'EXCEPTION', E}

This operation installs the cosNotification application.

install(Seconds) -> Return

Types:
Return = ok | {'EXCEPTION', E}

This operation installs the cosNotification application using Seconds delay between each block, currently 6, of IFR-registrations. This approach spreads the IFR database access over a period of time to allow other applications to run smother.

install_event() -> Return

Types:
Return = ok | {'EXCEPTION', E}

This operation installs the necessary cosEvent interfaces. If cosEvent is already installed this operation may not be used.

install_event(Seconds) -> Return

Types:
Return = ok | {'EXCEPTION', E}

This operation installs the necessary cosEvent interfaces using Seconds delay between each block of IFR-registrations. If cosEvent is already installed this operation may not be used.

uninstall() -> Return

Types:
Return = ok | {'EXCEPTION', E}

This operation uninstalls the cosNotification application.

uninstall(Seconds) -> Return

Types:
Return = ok | {'EXCEPTION', E}

This operation uninstalls the cosNotification application using Seconds delay between each block, currently 6, of IFR-unregistrations. This approach spreads the IFR database access over a period of time to allow other applications to run smother.

uninstall_event() -> Return

Types:
Return = ok | {'EXCEPTION', E}

This operation uninstalls the inherrited cosEvent interfaces. If cosEvent is in use this function may not be used.

uninstall_event(Seconds) -> Return

Types:
Return = ok | {'EXCEPTION', E}

This operation uninstalls the inherrited cosEvent interfaces, using Seconds delay between each block of IFR-unregistrations. If cosEvent is in use this function may not be used.

start() -> Return

Types:
Return = ok | {error, Reason}

This operation starts the cosNotification application.

stop() -> Return

Types:
Return = ok | {error, Reason}

This operation stops the cosNotification application.

start_global_factory() -> ChannelFactory

Types:
ChannelFactory = #objref

This operation creates a Event Channel Factory should be used for a multi-node Orber. The Factory is used to create a new channel.

start_global_factory(Options) -> ChannelFactory

Types:
Options = [Option]
Option = {pullInterval, Seconds} | {filterOp, Op} | {gcTime, Seconds} | {gcLimit, Anount} | {timeService, #objref}
ChannelFactory = #objref

This operation creates a Event Channel Factory and should be used for a multi-node Orber. The Factory is used to create a new channel.

• {pullInterval, Seconds} - determine how often Proxy Pull Consumers will check for new events with the client application. The default value is 20 seconds.


• {filterOp, OperationType} - determine which type of Administrator objects should be started, i.e., 'OR_OP' or 'AND_OP'. The default value is 'OR_OP'.


• {timeService, TimeServiceObj | 'undefined'} - to be able to use Start and/or Stop QoS this option must be used. See the function start_time_service/2 in the cosTime application. The default value is 'undefined'.


• {filterOp, OperationType} - determine which type of Administrator objects should be started, i.e., 'OR_OP' or 'AND_OP'. The default value is 'OR_OP'.


• {gcTime, Seconds} - this option determines how often, for example, proxies will garbage collect expired events. The default value is 60.


• {gcLimit, Amount} - determines how many events will be stored before, for example, proxies will garbage collect expired events. The default value is 50. This option is tightly coupled with the QoS property MaxEventsPerConsumer, i.e., the gcLimit should be less than MaxEventsPerConsumer and greater than 0.

start_factory() -> ChannelFactory

Types:
ChannelFactory = #objref

This operation creates a Event Channel Factory. The Factory is used to create a new channel.

start_factory(Options) -> ChannelFactory

Types:
Options = [Option]
Option = {pullInterval, Seconds} | {filterOp, Op} | {gcTime, Seconds} | {gcLimit, Amount} | {timeService, #objref}
ChannelFactory = #objref

This operation creates a Event Channel Factory. The Factory is used to create a new channel.

stop_factory(ChannelFactory) -> Reply

Types:
ChannelFactory = #objref
Reply = ok | {'EXCEPTION', E}

This operation stop the target channel factory.

start_filter_factory() -> FilterFactory

Types:
FilterFactory = #objref

This operation creates a Filter Factory. The Factory is used to create a new Filter's and MappingFilter's.

stop_filter_factory(FilterFactory) -> Reply

Types:
FilterFactory = #objref
Reply = ok | {'EXCEPTION', E}

This operation stop the target filter factory.
