Detailed Description

The conversion service interface allows to:

Add, get and remove data converters from the service.
Create objects using converters: e.g. create the transient representation of a persistent object.
convert objects - the opposite of create: e.g. convert transient objects into the persistent representation of these objects. The objects to be converted are defined by a data selector object.
update objects which already exist: e.g. update the existing persistent representation of objects which were read from the persistent store and should be modified. The objects to be converted are defined by a data selector object.
Class specific aspects of the creation/update/conversion mechanism must be handled by the converters, the common aspects will be handled by the service.

Member Function Documentation

virtual StatusCode IConversionSvc::addConverter ( IConverter * pConverter )

pure virtual

Add converter object to conversion service.

Parameters

pConverter Pointer to converter object

Returns: Status code indicating success or failure.

Implemented in PersistencySvc, and ConversionSvc.

virtual StatusCode IConversionSvc::addConverter ( const CLID & clid )

pure virtual

Add converter object to conversion service.

Parameters

clid	Class ID of the converter needed

Returns: Status code indicating success or failure.

Implemented in PersistencySvc, and ConversionSvc.

virtual StatusCode IConversionSvc::commitOutput	(	const std::string &	outputFile,
		bool	do_commit
	)

pure virtual

Commit pending output.

Parameters

outputFile	String containing output file
do_commit	if true commit the output and flush eventually pending items to the database if false, discard pending buffers. Note: The possibility to commit or roll-back depends on the database technology used!

Returns: Status code indicating success or failure.

Implemented in PersistencySvc, ConversionSvc, and Gaudi::RootCnvSvc.

virtual StatusCode IConversionSvc::connectOutput ( const std::string & outputFile )

pure virtual

Connect the output file to the service.

Parameters

outputFile String containing output file

Returns: Status code indicating success or failure.

Implemented in PersistencySvc, ConversionSvc, and Gaudi::RootCnvSvc.

virtual StatusCode IConversionSvc::connectOutput	(	const std::string &	outputFile,
		const std::string &	openMode
	)

pure virtual

Connect the output file to the service with open mode.

Parameters

outputFile	String containing output file
openMode	String containing opening mode of the output file

Returns: Status code indicating success or failure.

Implemented in PersistencySvc, ConversionSvc, and Gaudi::RootCnvSvc.

virtual IConverter* IConversionSvc::converter ( const CLID & clid )

pure virtual

Retrieve converter from list.

Parameters

clid	the clid of the converter

Returns: the converter corresponding to clid or 0 if none was found

Implemented in PersistencySvc, and ConversionSvc.

IConversionSvc::DeclareInterfaceID	(	IConversionSvc	,
		4	,
		0
	)

InterfaceID.

virtual StatusCode IConversionSvc::removeConverter ( const CLID & clid )

pure virtual

Remove converter object from conversion service (if present).

The converter is defined by the class type of the objects created.

Parameters

clid	Class ID of the converter

Returns: Status code indicating success or failure.

Implemented in PersistencySvc, and ConversionSvc.
