Function Documentation

template<class T>

T Min	(	const T &	a_a,
		const T &	a_b
	)			[inline]

Returns a copy of the minimum of the two values. Will work with any type T that supplies a T::operator<(const T, const T), or an equivalent construct, as well as a copy constructor. In particular, it will work with any integral or floating-point intrinsic type.

Referenced by IFData< dim >::BrentRootFinder(), EBPatchAdvect::floorPrimitives(), RealVect::min(), and IntVect::min().

template<class T>

T Max	(	const T &	a_a,
		const T &	a_b
	)			[inline]

Returns a copy of the maximum of the two values. Will work with any type T that supplies a T::operator>(const T, const T), or an equivalent construct, as well as a copy constructor. In particular, it will work with any integral or floating-point intrinsic type.

template<class T>

T Abs

(

const T &

a_a

)

[inline]

Returns a copy of the absolute value of the value. Will work with any type T that can be compared against zero with T::operator>(const T, const T), or an equivalent construct, as well as a copy constructor, and an T::operator-() or equivalent. In particular, it will work with any integral or floating-point intrinsic type.

template<class T>

void Swap	(	T &	a_a,
		T &	a_b
	)			[inline]

Swaps the two values. Type T must have a copy constructor and an assignment operator.
