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.
Return = ok | {'EXCEPTION', E} | {'EXIT', R}This operation installs the cosEvent application.
Return = ok | {'EXCEPTION', E} | {'EXIT', R}This operation uninstalls the cosEvent application.
Return = ok | {error, Reason}This operation starts the cosEvent application.
Return = ok | {error, Reason}This operation stops the cosEvent application.
Channel = #objrefThis operation creates a new instance of a Event Channel using the default settings.
start_channel(Options) -> Channel
Options = [Option]Option = {pull_interval, Seconds} | {typecheck, Boolean} |
{maxEvents, Integer} | {blocking, Boolean}Channel = #objrefThis 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
Channel = #objrefThis 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
Options = [Option]Option = {pull_interval, Seconds} | {typecheck, Boolean} |
{maxEvents, Integer} | {blocking, Boolean}Channel = #objref 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
Channel = #objrefReply = ok | {'EXCEPTION', E}This operation stop the target event channel.
