Detailed Description

template<typename D, typename T, typename B>
class macstl::impl::vec_base< D, T, B >

Base for vec class.

For internal use only.

This class defines all the common member and friend functions for vec, an interface similar to valarray.

Parameters:

	D	Raw vector data type e.g. __vector unsigned int (Altivec) or __m128i (SSE2).
	T	Scalar element type e.g. unsigned int.
	B	Scalar element type for logical function results e.g. boolean <int>.

Note:

Uses the Barton-Nackman trick to expose friend functions, so that you can use raw data types interchangeably with the vector object. Operators are only defined for the vector when they are defined for the element types, e.g. operator~ is not defined for vec <float, 4> since operator~ is not defined for float.

Public Types
typedef B	boolean_type
	Scalar element type for logical function results.
typedef D	data_type
	Raw vector data type.
typedef T	value_type
	Scalar element type.
typedef vec< B, length >	vec_boolean
	Object vector data type for logical function results.
typedef vec< T, length >	vec_value
	Object vector data type. This should be the subclass.

void	operator= (data_type lhs)
	Assigns the raw data lhs.
value_type	operator[] (std::size_t i) const
	Gets the element at index i.
reference	operator[] (std::size_t i)
	Gets a reference to the element at index i.
const vec_value	shift (int i) const
