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 in DateTime, Double, Float, Int, and String.

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 in Bool, DateTime, Double, Float, Int, and String.

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 in Bool, DateTime, Double, Float, Int, and String.

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 in Bool, DateTime, Double, Float, Int, and String.

virtual void* getRef ( ) const throw (APIException) [pure virtual]

Get pointer to C++ member.

Exceptions:

APIException

if updateRef was not called before

Implemented in StoreableFilter, StoreableFilter< double >, StoreableFilter< std::string >, StoreableFilter< float >, StoreableFilter< int >, StoreableFilter< bool >, and StoreableFilter< tm >.

virtual bool isNull ( ) const [pure virtual]

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

Returns:: true if NULL should be stored, false otherwise

Implemented in Bool, DateTime, Double, Float, Int, and String.

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

Convert type to string.

Should throw dba::StoreableFilterException if conversion fails

Parameters:

pSpec

conversion parameters dependent of used database

Returns:: converted value.

Implemented in Bool, DateTime, Double, Float, Int, and String.

virtual void updateRef ( void * pNewMember ) [pure virtual]

Update pointer to C++ member to new address.

This method is used by dba just before filter usage.

Parameters:

pNewMember

address of new member

Implemented in StoreableFilter, StoreableFilter< double >, StoreableFilter< std::string >, StoreableFilter< float >, StoreableFilter< int >, StoreableFilter< bool >, and StoreableFilter< tm >.
