Member Function Documentation

template<class TOutput >

virtual void FieldHandlerBase< TOutput >::extractValue	(	const AttributeList &	src,
		TOutput &	dest
	)		[pure virtual]

The actual extraction function. src contains a CORAL attribute list representing a query result row, dest is the output object to be filled.

Implemented in FieldHandler< TOutput, TCField, TDBField >, ASCIIBoolFieldHandler< TOutput, FalseCharacter >, and FieldHandler< TOutput, bool, char >.

(

)

[inline, virtual]

Return the name of the associated database field. For the GMT database, this simply corresponds to the uppercased field name.
