Member Function Documentation

template<class T> bool Comparator< T >::isEqual (  const T &  a, const T &  b )  const throw () [virtual]

Test if two values are equal.

template<class T> bool Comparator< T >::isGreater (  const T &  a, const T &  b )  const throw ()

Test if a is greater then b.

template<class T> bool Comparator< T >::isGreaterOrEqual (  const T &  a, const T &  b )  const throw ()

Test if a is greater or equal.

template<class T> bool Comparator< T >::isLess (  const T &  a, const T &  b )  const throw () [virtual]

Test if a is less then b.

template<class T> bool Comparator< T >::isLessOrEqual (  const T &  a, const T &  b )  const throw ()

Test if a is less or equal.

template<class T> bool Comparator< T >::isNotEqual (  const T &  a, const T &  b )  const throw ()

Test if two values are unequal.

template<class T> int Comparator< T >::operator() (  const T &  a, const T &  b )  const throw ()

Compare two values. -1 is returned if a < b. 0 is returned if a == b. 1 is returned if a > b.
