Detailed Description

template<class T, unsigned int NCOL>
class CdbNTupleIsLessComparator< T, NCOL >

An abstract base class for the "isLess" comparator of two rows in an n-tuple.

This class provides a base interface for actual implementations of the comparision operation carrying a user defined semantics.

NOTE: Although the number of columns parameter is not directly used in this interface it's still requires as it may be used in actual implementation of the comparision operation. This will also enforce using the right comparator class matching the n-tuple with the same signature.

template<class T, unsigned int NCOL> CdbNTupleIsLessComparator< T, NCOL >::~CdbNTupleIsLessComparator (    )  [virtual]

Member Function Documentation

template<class T, unsigned int NCOL> virtual bool CdbNTupleIsLessComparator< T, NCOL >::isLess (  const std::vector< T > &    theLeftRow, const std::vector< T > &    theRightRow )  const [pure virtual]

Compare two rows. This method has to be implemented by a subclass. The method will return "true" if "theLeftRow" is strictly less than "theRightRow". Implemented in CdbNTupleIsLessComparatorDefaultImpl< T, NCOL >.
