indirect_array (const indirect_array &)
Copy constructor. Both slices refer to the same underlying array.

template<class _Dom > void operator%= (const _Expr< _Dom, _Tp > &) const

void operator%= (const *valarray*< _Tp > &) const
Modulo slice elements by corresponding elements of v.

template<class _Dom > void operator&= (const _Expr< _Dom, _Tp > &) const

void operator&= (const *valarray*< _Tp > &) const
Logical and slice elements with corresponding elements of v.

template<class _Dom > void operator*= (const _Expr< _Dom, _Tp > &) const

void operator*= (const *valarray*< _Tp > &) const
Multiply slice elements by corresponding elements of v.

template<class _Dom > void operator+= (const _Expr< _Dom, _Tp > &) const

void operator+= (const *valarray*< _Tp > &) const

void operator-= (const *valarray*< _Tp > &) const
Subtract corresponding elements of v from slice elements.

template<class _Dom > void operator/= (const _Expr< _Dom, _Tp > &) const

void operator/= (const *valarray*< _Tp > &) const

void operator= (const _Tp &) const
Assign all slice elements to t.

indirect_array & operator= (const indirect_array &)
Assignment operator. Assigns elements to corresponding elements of a.

void operator= (const *valarray*< _Tp > &) const

Detailed Description

“template<class _Tp>

class std::indirect_array< _Tp >“Reference to arbitrary subset of an array.

An indirect_array is a reference to the actual elements of an array specified by an ordered array of indices. The way to get an indirect_array is to call operator[](valarray<size_t>) on a valarray. The returned indirect_array then permits carrying operations out on the referenced subset of elements in the original valarray.

For example, if an indirect_array is obtained using the array (4,2,0) as an argument, and then assigned to an array containing (1,2,3), then the underlying array will have array[0]==3, array[2]==2, and array[4]==1.

Parameters

Tp Element type.
