cosNotificationApp The main module of the cosNotification application.

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.

 install() -> Return Install the cosNotification application Return = ok | {'EXCEPTION', E}

This operation installs the cosNotification application.

 install(Seconds) -> Return Install the cosNotification application 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 Install the necessary cosEvent interfaces Return = ok | {'EXCEPTION', E}

This operation, which may only be used if it is impossible to upgrade to cosEvent-2.0 or later, installs the necessary cosEvent interfaces. If cosEvent-2.0 is available, use cosEventApp:install() instead.

 install_event(Seconds) -> Return Install the necessary cosEvent interfaces Return = ok | {'EXCEPTION', E}

This operation, which may only be used if it is impossible to upgrade to cosEvent-2.0 or later, installs the necessary cosEvent interfaces using Seconds delay between each block of IFR-registrations. If cosEvent-2.0 is available, use cosEventApp:install() instead.

 uninstall() -> Return Uninstall the cosNotification application Return = ok | {'EXCEPTION', E}

This operation uninstalls the cosNotification application.

 uninstall(Seconds) -> Return Uninstall the cosNotification application 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 Uninstall the inherited cosEvent interfaces Return = ok | {'EXCEPTION', E}

This operation uninstalls the inherited cosEvent interfaces. If cosEvent is in use this function may not be used. This function may only be used if cosNotificationApp:install_event/1/2 was used. If not, use cosEventApp:uninstall() instead.

 uninstall_event(Seconds) -> Return Uninstall the inherited cosEvent interfaces Return = ok | {'EXCEPTION', E}

This operation uninstalls the inherited cosEvent interfaces, using Seconds delay between each block of IFR-unregistrations. If cosEvent is in use this function may not be used. This function may only be used if cosNotificationApp:install_event/1/2 was used. If not, use cosEventApp:uninstall() instead.

 start() -> Return Start the cosNotification application Return = ok | {error, Reason}

This operation starts the cosNotification application.

 stop() -> Return Stop the cosNotification application Return = ok | {error, Reason}

This operation stops the cosNotification application.

 start_global_factory() -> ChannelFactory Start a global channel factory as default 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 Start a global channel factory with options 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 Start a channel factory as default ChannelFactory = #objref

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

start_factory(Options) -> ChannelFactory Start a channel factory with options 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 Terminate the target object ChannelFactory = #objref Reply = ok | {'EXCEPTION', E}

This operation stop the target channel factory.

 start_filter_factory() -> FilterFactory Start a filter factory 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 Terminate the target object FilterFactory = #objref Reply = ok | {'EXCEPTION', E}

This operation stop the target filter factory.

 create_structured_event(Domain, Type, Event, VariableHeader, FilterableBody, BodyRemainder) -> Reply Create a structured event Domain = string() Type = string() Event = string() VariableHeader = [CosNotification::Property] FilterableBody = [CosNotification::Property] BodyRemainder = #any data-type Reply = CosNotification::StructuredEvent | {'EXCEPTION', E}

An easy way to create a structured event is to use this function. Simple typechecks are performed and if one of the arguments is not correct a 'BAD_PARAM' exception is thrown.

 type_check() -> Reply Return the value of the configuration parameter type_check Reply = true | false

This operation returns the value of the configuration parameter type_check.
