EXPORTS

install() -> Return
 
Types:
Return = ok | {'EXCEPTION', E} | {'EXIT', R}
 
This operation installs the cosEvent application.
uninstall() -> Return
 
Types:
Return = ok | {'EXCEPTION', E} | {'EXIT', R}
 
This operation uninstalls the cosEvent application.
start() -> Return
 
Types:
Return = ok | {error, Reason}
 
This operation starts the cosEvent application.
stop() -> Return
 
Types:
Return = ok | {error, Reason}
 
This operation stops the cosEvent application.
start_channel() -> Channel
 
Types:
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
 
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
 
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
 
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}
 
This operation stop the target event channel.
