Member Function Documentation

virtual void fromDate ( const ConvSpec &  pSpec,
const tm &  pDate 
) throw (StoreableFilterException) [virtual]

Convert to C++ type from int value received from database.

Should throw dba::StoreableFilterException if conversion fails Must be implemented for BIND_DAT usage

Parameters:
pSpec conversion parameters dependent of used database
pDate source value for conversion

Reimplemented from StoreableFilterBase.

virtual void fromDouble ( const ConvSpec &  pSpec,
double  pData 
) throw (StoreableFilterException) [virtual]

Convert to C++ type from double value received from database.

Should throw dba::StoreableFilterException if conversion fails Must be implemented for BIND_FLT usage

Parameters:
pSpec conversion parameters dependent of used database
pData source value for conversion

Reimplemented from StoreableFilterBase.

virtual void fromInt ( const ConvSpec &  pSpec,
int  pData 
) throw (StoreableFilterException) [virtual]

Convert to C++ type from int value received from database.

Should throw dba::StoreableFilterException if conversion fails Must be implemented for BIND_INT usage

Parameters:
pSpec conversion parameters dependent of used database
pData source value for conversion

Reimplemented from StoreableFilterBase.

virtual void fromString ( const ConvSpec &  pSpec,
const std::string &  pData 
) throw (StoreableFilterException) [virtual]

Convert to C++ type from std::string value received from database.

Should throw dba::StoreableFilterException if conversion fails Must be implemented for BIND_STR usage

Parameters:
pSpec conversion parameters dependent of used database
pData source value for conversion

Reimplemented from StoreableFilterBase.

virtual bool isNull (  )  const [virtual]

Check if C++ type should be stored as NULL value in database.

Returns:
true if NULL should be stored, false otherwise

Implements StoreableFilterBase.

virtual std::string toString ( const ConvSpec &  pSpec  )  const throw (StoreableFilterException) [virtual]

Convert type to string.

Should throw dba::StoreableFilterException if conversion fails

Parameters:
pSpec conversion parameters dependent of used database
Returns:
converted value.

Implements StoreableFilterBase.
