extractValue()

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

getColumnName()

template<class TOutput >

virtual const std::string FieldHandlerBase< TOutput >::getColumnName ( )

inlinevirtual

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