Designing SCOadmin object service agents

BMIP request processor

Each OSA can control how the implementation of BMIP requests is actually performed. This is performed by informing the Server API about an OSAs request processor. The implementation of an OSAs request processor is optional, and should only be implemented if the OSA needs some special functionality such as synchronization, scoping or first pass validation.

By providing a request processor, the OSA is taking over control of processing the BMIP requests from the Server API. In the very least this entails:

running a filter via OFEvaluateFilter(TCL_ADM) on the object instance(s).
executing the specified operation on the object instance(s) via OFEvaluateOperation(TCL_ADM).
returning a BMIP response to the client via OFReturnBmipResponse(TCL_ADM).

The request processor is the only place an OSA class can implement scoping or synchronization. In addition to the minimal operation set, the following features can be added by the user.
