Constructor Detail

DriverGenericMMGeneric

public DriverGenericMMGeneric()

Create a bare instance of the driver. It is not functional until a database connection has been supplied via setConnection.

Method Detail

supportsMultipleModels

public boolean supportsMultipleModels()

Returns true of the database layout supports multiple RDF models in the same database.

Specified by:

supportsMultipleModels in interface IRDBDriver

Overrides:

supportsMultipleModels in class DriverGenericGeneric

allocateModelID

public IDBID allocateModelID(java.lang.String modelName)
                      throws RDFRDBException

Allocate a new databaseID for a new model in the same database. Unlike other allcoate calls this also record the allocation in the database directly. Throws RDFRDBException if the driver does not support multiple models per db.

Specified by:

allocateModelID in interface IRDBDriver

Overrides:

allocateModelID in class DriverGenericGeneric

getModelID

public IDBID getModelID(java.lang.String modelName)
                 throws RDFRDBException

Return the databaseID for an existing named model within the database. Throws RDFRDBException if the driver does not support multiple models per db.

Specified by:

getModelID in interface IRDBDriver

Overrides:

getModelID in class DriverGenericGeneric

listModels

public java.util.Iterator listModels()
                              throws RDFRDBException

List the names of all models in this database

Specified by:

listModels in interface IRDBDriver

Overrides:

listModels in class DriverGenericGeneric
