AR Filter API plug-ins introduction
AR System Filter (AR Filter) API plug-ins enable you to create tight, efficient integrations between your systems and the AR System server. They are triggered with Set Field actions in filters and escalations. Because this middleware is loaded as a plug-in when BMC Remedy AR System is started instead of as a stand-alone executable at each event, it consumes fewer resources and less processor time than a Set Fields $PROCESS$ action.
You use Developer Studio to create AR Filter Set Field actions in filters and escalations.
At run time, the AR System server sends AR Filter API requests to the plug-in, which directs the requests to the appropriate plug-in. The plug-in processes the input arguments and can return values that can be used in the Set Fields action.
When you enter AR Filter API requests in the Create Filter form, the AR System server sends the requests to the plug-in, which sends them to AR Filter. AR Filter either processes the data or request itself or retrieves output data from the external data source and returns it in the opposite direction.
Unlike AREA plug-ins, multiple AR Filter API plug-ins can be loaded simultaneously by the plug-in server.
The following figure shows the flow of requests and information for AR Filter API plug-ins.
