Detailed Description

The implementation of IGslSvc interface.

The Gsl Service is teh service which perform intelligent error handling for GSL (GNU Scientific Library)

It provides a choice between different "Error Handling Policies"

Current implementation supports the several "error handling policies", which are driven by "ErrorPolicy" property of class GslSvc:

• "GSL": The simplest error policy, no action, the error hadling defined in GSL does not redefined
• "Off": The GSL empty error handling is used, what means the ignorance of all GSL errors. Program continues after any error, so the return values from any library routines must be checked. This policy is recommended by GSL team for production programs
• "Abort" The default GSL error policy, causes abort on error.
• "Ignore" The policy which is essentially the same as "Off", but performed with local error handler GslErrorHandlers::ignoreTheError
• "Exception" This policy throws the GaudiException with tag *GSL Error" to be thrown at the error. The policy implemented by local error handler GslErrorHandlers::throwException
• "Handle" The policy which uses the call back from local error handler GslErrorHandlers::handleTheError to IGslSvc::handle method. Current implementation of this method is sequential execution of declared handlers, defined through the property "Handlers" of class GslSvc in a format: GslSvc.Handlers = { "H1Type/H1Name" , "H2Type/H2Name" , "H3ype/3Name" }; The "handlers" must implement IGslErrorHandler interface The concrete handlers are provided in GaudiGSL package: class GslErorCount, GslErrorPrint and GslErrorException.

Attention

The error handling could be "turned off" for selected error codes (e.g. GSL_SUCCESS or GSL_CONTINUE ) using "IgnoreCodes" property. This feature is active only for "Handle" error policy.
