Constructor Details

Driver

public Driver()

Creates a Driver.

Driver

protected Driver(@Nullable Supplier<CalcitePrepare> prepareFactory)

Creates a Driver with a factory for CalcitePrepare objects; if the factory is null, the driver will call CalcitePrepare.DEFAULT_FACTORY.

Method Details

withPrepareFactory

public Driver withPrepareFactory(Supplier<CalcitePrepare> prepareFactory)

Creates a copy of this Driver with a new factory for creating CalcitePrepare.

Allows users of the Driver to change the factory without subclassing the Driver. But subclasses of the driver should override this method to create an instance of their subclass.

Parameters:

prepareFactory - Supplier of a CalcitePrepare

Returns:

Driver with the provided prepareFactory

createPrepare

public CalcitePrepare createPrepare()

Creates a CalcitePrepare to be used to prepare a statement for execution.

If you wish to use a custom prepare, either override this method or call withPrepareFactory(Supplier).

createPrepareFactory

@Deprecated
protected Function0<CalcitePrepare> createPrepareFactory()

Deprecated.

Returns a factory with which to create a CalcitePrepare.

Now deprecated; if you wish to use a custom prepare, please call withPrepareFactory(Supplier) or override createPrepare().
