virtual TCollection_ExtendedString CDF_MetaDataDriver::BuildFileName ( const Handle< CDM_Document > & aDocument )

pure virtual

Implemented in CDF_FWOSDriver.

virtual void CDF_MetaDataDriver::CreateDependsOn	(	const Handle< CDM_MetaData > &	aFirstData,
		const Handle< CDM_MetaData > &	aSecondData
	)

virtual

Creates a "Depends On" relation between two Datas. By default does nothing.

virtual Handle< CDM_MetaData > CDF_MetaDataDriver::CreateMetaData	(	const Handle< CDM_Document > &	aDocument,
		const TCollection_ExtendedString &	aFileName
	)

pure virtual

should create meta-data corresponding to aData and maintaining a meta-link between these meta-data and aFileName CreateMetaData is called by CreateData If the metadata-driver has version capabilities, version must be set in the returned Data.

virtual void CDF_MetaDataDriver::CreateReference	(	const Handle< CDM_MetaData > &	aFrom,

virtual TCollection_ExtendedString CDF_MetaDataDriver::DefaultFolder ( )

pure virtual

Implemented in CDF_FWOSDriver.

virtual Standard_Boolean CDF_MetaDataDriver::Find	(	const TCollection_ExtendedString &	aFolder,
		const TCollection_ExtendedString &	aName,
		const TCollection_ExtendedString &	aVersion
	)

pure virtual

should indicate whether meta-data exist in the DBMS corresponding to the Data. aVersion may be NULL;

Implemented in CDF_FWOSDriver.

Standard_Boolean CDF_MetaDataDriver::Find	(	const TCollection_ExtendedString &	aFolder,
		const TCollection_ExtendedString &	aName

	)

virtual

by default return Standard_True.

virtual Standard_Boolean CDF_MetaDataDriver::HasVersionCapability ( )

virtual

returns true if the MetaDataDriver can manage different versions of a Data. By default, returns Standard_False.

virtual Handle< CDM_MetaData > CDF_MetaDataDriver::LastVersion ( const Handle< CDM_MetaData > & aMetaData )

virtual

by default returns aMetaDATA should return the MetaData stored in the DBMS with the meta-data corresponding to the path. If the MetaDataDriver has version management capabilities the version has to be set in the returned MetaData. MetaData is called by GetMetaData If the version is not included in the path , MetaData should return the last version of the metadata is deferred;

virtual Handle< CDM_MetaData > CDF_MetaDataDriver::MetaData	(	const TCollection_ExtendedString &	aFolder,

pure virtual

should return the MetaData stored in the DBMS with the meta-data corresponding to the Data. If the MetaDataDriver has version management capabilities the version has to be set in the returned MetaData. aVersion may be NULL MetaData is called by GetMetaData If the version is set to NULL, MetaData should return the last version of the metadata

Handle< CDM_MetaData > CDF_MetaDataDriver::MetaData	(	const TCollection_ExtendedString &	aFolder,

virtual

virtual TCollection_ExtendedString CDF_MetaDataDriver::SetName	(	const Handle< CDM_Document > &	aDocument,
		const TCollection_ExtendedString &	aName
	)

virtual

this methods is usefull if the name of an object – depends on the metadatadriver. For example a Driver – based on the operating system can choose to add the extension of file to create to the object.
