List of all members.

Public Types
typedef size_transformer < trans_type_, typename array_type_::size_type > ::size_type	size_type
	The size type of the resulting array.
typedef detail::size_to_signature < size_type, typename array_type_::value_type > ::type	signature
	The signature of the resulting array.
typedef array_type_::traits_type	traits_type
	The traits type of the resulting array which is the same as the traits type of the original array.
typedef iterator_transformer < trans_type_, typename array_type_::iterator, typename array_type_::size_type > ::iterator_type	iterator
	The iterator type of the resulting array.
typedef iterator_transformer < trans_type_, typename array_type_::const_iterator, typename array_type_::size_type > ::iterator_type	const_iterator
	The const iterator type of the resulting array.
typedef ::lite::array < signature, traits_type, reference_rep< iterator > >	array
	The exact type of the resulting array when the transform is applied to a non-const array object.
typedef ::lite::array < signature, traits_type, reference_rep< const_iterator > >	const_array
	The exact type of the resulting array when the transform is applied to a const array object.
typedef array_helper < signature, traits_type > ::temporary_array	temporary_array
	An array type compatible with the resulting array (i.e. with the same signature and traits). Suitable for defining temporary variables or return types.
typedef array_helper < signature, traits_type > ::fwd_temporary_array	fwd_temporary_array
	An array type compatible with the resulting array (i.e. with the same signature and traits) and with forward storage. Suitable for defining temporary variables or return types.
typedef array_helper < signature, traits_type > ::rev_temporary_array	rev_temporary_array
	An array type compatible with the resulting array (i.e. with the same signature and traits) and with reverse storage. Suitable for defining temporary variables or return types.

Detailed Description

template<typename array_type_, typename trans_type_>
struct lite::transform_traits< array_type_, trans_type_ >

This class provides information about applying a transform object to an array object. It can be used for example to get the exact type of the array that is returned as the result of applying a transform.

Example

        typedef array<float[5][5]> A;
    
        A a;

        transform_traits<A, row>::array a_r1 = a[row(1)];

        a_r1 = -1;
        // the previous line is equivalent to:
        a[row(1)] = -1;

        transform_traits<A, row>::temporary_array a_rt = a[row(1)];
        a[row(1)] = a[row(2)];
        a[row(2)] = a_rt;
        // the previous 3 lines is equivalent to:
        swap(a[row(1)], a[row(2)]);
