Member Function Documentation

virtual void hk_data::before_connection_disconnects ( void ) [protected, virtual]

Reimplemented in hk_datasource.

virtual void hk_data::before_source_vanishes ( void ) [protected, virtual]

Reimplemented in hk_actionquery, and hk_datasource.

virtual bool hk_data::driver_specific_name ( const hk_string & n ) [protected, virtual]

virtual void hk_data::filelist_changes ( listtype t ) [protected, virtual]

Reimplemented in hk_datasource.

hk_string hk_data::identifierdelimiter ( void ) const [inline]

virtual hk_string hk_data::name ( void ) const [virtual]

name of the Datasource. If the datasource is of type "Table","Query", this name will be used to create automatically a SQL-statement : "SELECT * FROM <name>"
