vctFixedSizeVectorRecursiveEngines< _size >::VoSiVi< _elementOperationType > Class Template Reference

#include <vctFixedSizeVectorRecursiveEngines.h>

List of all members.

Detailed Description

template<vct::size_type _size>
template<class _elementOperationType>
class vctFixedSizeVectorRecursiveEngines< _size >::VoSiVi< _elementOperationType >

Implement operation of the form $v_o = op(s_i, v_i)$

for fixed size vectors.

This class uses template specialization to perform binary vector operations of the form

$v_o = \mathrm{op}(s_i, v_i)$

where $v_o$ is the output vector, and $s_i, v_i$ are input scalar and vector, all vectors are of an equal fixed size, determined at compilation time, op stands for the a binary operation performed elementwise between $s_i$ and $v_i$ , and whose result is stored elementwise into $v_o$ .

The operation type operationType must have a static method with the signature

      static operationType Operation(const I1E & arg1, const I2E & arg2)

where OE, I1E, I2E are the types of vector elements in $v_o, v_i s_i$ respectively. These types do not need to be defined explicitly for vctFixedSizeVectorRecursiveEngines class, as they are inferred from the signature of the corresponding operator[] for each of the vector types. However, they may need to be defined for the class operationType.

For examples of binary operations, see vctBinaryOperations.h .

Usage example for vctFixedSizeVectorRecursiveEngines::VoSiVi:

      enum {SIZE = 3};
      int input1[SIZE];
      float a;
      double output[SIZE];

      vctFixedSizeVectorRecursiveEngines<SIZE>::VoSiVi<vctBinaryOperations<int,float,double>::Addition>Unfold(output, scalar, input1);

stores the sum of elements of s and input1 into output.

Parameters:

_elementOperationType

The type of the binary operation.

static void vctFixedSizeVectorRecursiveEngines< _size >::VoSiVi< _elementOperationType >::Unfold	(	_outputVectorType &	output,
		const _inputScalarType &	inputScalar,
		const _inputVectorType	inputVector
	)			`[inline, static]`

Unfold the recursion. Performs the operation _elementOperationType elementwise on the last elements of the input vector and scalar and call Unfold for the _size - 1 elements left (i.e. unfold the recursive calls).

Parameters:

	output	The output vector.
	inputScalar	The input scalar (first operand).
	inputVector	The input vector (second operand).
