bool BALL::Comparator< T >::isGreaterOrEqual	(	const T &	a,
		const T &	b
	)			const [inline]

Test if a is greater or equal.

template<class T >

bool BALL::Comparator< T >::isLess	(	const T &	a,
		const T &	b
	)			const [inline, virtual]

Test if a is less then b.

template<class T >

bool BALL::Comparator< T >::isLessOrEqual	(	const T &	a,
		const T &	b
	)			const [inline]

Test if a is less or equal.

template<class T >

bool BALL::Comparator< T >::isNotEqual	(	const T &	a,
		const T &	b
	)			const [inline]

Test if two values are unequal.

References BALL::Comparator< T >::isEqual().

template<class T >

int BALL::Comparator< T >::operator()	(	const T &	a,
		const T &	b
	)			const [inline]

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

0 is returned if a == b.

1 is returned if a > b.
