DESCRIPTION
To get access to the record definitions for the structures use:
-include_lib("cosEvent/include/*.hrl").
This module contains the functions for starting and stopping the application.
EXPORTS
install() -> Return
-
Types:
-
Return = ok | {'EXCEPTION', E} | {'EXIT', R}
-
Return = ok | {'EXCEPTION', E} | {'EXIT', R}
-
This operation installs the cosEvent application.
uninstall() -> Return
-
Types:
-
Return = ok | {'EXCEPTION', E} | {'EXIT', R}
-
Return = ok | {'EXCEPTION', E} | {'EXIT', R}
-
This operation uninstalls the cosEvent application.
start() -> Return
-
Types:
-
Return = ok | {error, Reason}
-
Return = ok | {error, Reason}
-
This operation starts the cosEvent application.
stop() -> Return
-
Types:
-
Return = ok | {error, Reason}
-
Return = ok | {error, Reason}
-
This operation stops the cosEvent application.
start_channel() -> Channel
-
Types:
-
Channel = #objref
-
Channel = #objref
-
This operation creates a new instance of a Event Channel using the default settings.
start_channel(Options) -> Channel
-
Types:
-
Options = [Option]
Option = {pull_interval, Seconds} | {typecheck, Boolean} | {maxEvents, Integer} | {blocking, Boolean}
Channel = #objref
-
Options = [Option]
-
This operation creates a new instance of a Event Channel
-
- *
- {pull_interval, Seconds} - determine how often Proxy Pull Consumers will check for new events with the client application. The default value is 20 seconds.
- *
- {typecheck, Boolean} - if this option is set to true the proxies will check if the supplied client object is of correct type. The default value is false.
- *
- {maxEvents, Integer} - this option determine how many events the ProxyPullSuppliers will store before discarding events. If the limit is reached events will be discarded in any order. The default value is 300.
- *
- {blocking, Boolean} - this option determine the behavior of the channel when handling events internally. If set to true the risk of a single event supplier floods the system is reduced, but the performance may also be reduced. The default value is true.
-
start_channel_link() -> Channel
-
Types:
-
Channel = #objref
-
Channel = #objref
-
This operation creates a new instance of a Event Channel, which is linked to the invoking process, using the default settings.
start_channel_link(Options) -> Channel
-
Types:
-
Options = [Option]
Option = {pull_interval, Seconds} | {typecheck, Boolean} | {maxEvents, Integer} | {blocking, Boolean}
Channel = #objref
-
Options = [Option]
-
This operation creates a new instance of a Event Channel, which is linked to the invoking process, with settings defined by the given options. Allowed options are the same as for cosEventApp:start_channel/1.
stop_channel(Channel) -> Reply
-
Types:
-
Channel = #objref
Reply = ok | {'EXCEPTION', E}
-
Channel = #objref
-
This operation stop the target event channel.
