Detailed Description

Service interface.

A service should be used to provide constant or slowly changing per-event information, e.g. geometry with or without alignment, magnetic field, ..., and to handle once-per-run tasks. In contrast to an algorithm (i.e. inheriting from IAlgorithm), a service can have an internal state and each implementation has to ensure that concurrent calls are valid.

Member Function Documentation

virtual std::string FW::IService::name ( ) const

pure virtual

The service name.

Implemented in FW::BareService.

virtual void FW::IService::prepare ( AlgorithmContext &  ctx )

pure virtual

Prepare per-event information.

This is intended to add already existing information, e.g. geometry or conditions data, to the event store. While possible, complex operations should be better implemented as an regular algorithm.

Should throw an exception on non-recoverable errors.

Implemented in FW::BareService, and FW::HelloService.

virtual void FW::IService::startRun ( )

pure virtual

Start-of-run hook to be called before any events are processed.

Should throw an exception for non-recoverable errors.

Implemented in FW::BareService, and FW::HelloService.
