Method Detail

getDatabase

public Database<O> getDatabase(Normalization<O> normalization)

Description copied from interface: DatabaseConnection

Returns a Database according to parameter settings.

Parameters:

normalization - Normalization to perform a normalization if this action is supported. May remain null.

Returns:

a Database according to parameter settings

See Also:

DatabaseConnection.getDatabase(Normalization)

description

public String description()

Description copied from interface: Parameterizable

Returns a description of the class and the required parameters.

This description should be suitable for a usage description as for a standalone application.

Specified by:

description in interface Parameterizable

Overrides:

description in class AbstractParameterizable

Returns:

String a description of the class and the required parameters

Specified by:

setParameters in interface Parameterizable

Overrides:

setParameters in class AbstractDatabaseConnection<O extends DatabaseObject>

Parameters:

args - parameters to set the attributes accordingly to

Returns:

String[] an array containing the unused parameters

Throws:

ParameterException - in case of wrong parameter-setting

See Also:
