The start offset is the index of the first element of the array - * that is part of the subset. The size and stride array describe each - * dimension of the slice. Size is the number of elements in that - * dimension, and stride is the distance in the array between successive - * elements in that dimension. Each dimension's size and stride is taken - * to begin at an array element described by the previous dimension. The - * size array and stride array must be the same size. - * - * For example, if you have offset==3, stride[0]==11, size[1]==3, - * stride[1]==3, then slice[0,0]==array[3], slice[0,1]==array[6], - * slice[0,2]==array[9], slice[1,0]==array[14], slice[1,1]==array[17], - * slice[1,2]==array[20]. - */ - class gslice - { - public: - /// Construct an empty slice. - gslice (); - - /** - * @brief Construct a slice. - * - * Constructs a slice with as many dimensions as the length of the @a l - * and @a s arrays. - * - * @param o Offset in array of first element. - * @param l Array of dimension lengths. - * @param s Array of dimension strides between array elements. - */ - gslice(size_t, const valarray<size_t>&, const valarray<size_t>&); - - // XXX: the IS says the copy-ctor and copy-assignment operators are - // synthetized by the compiler but they are just unsuitable - // for a ref-counted semantic - /// Copy constructor. - gslice(const gslice&); - - /// Destructor. - ~gslice(); - - // XXX: See the note above. - /// Assignment operator. - gslice& operator=(const gslice&); - - /// Return array offset of first slice element. - size_t start() const; - - /// Return array of sizes of slice dimensions. - valarray<size_t> size() const; - - /// Return array of array strides for each dimension. - valarray<size_t> stride() const; - - private: - struct _Indexer { - size_t _M_count; - size_t _M_start; - valarray<size_t> _M_size; - valarray<size_t> _M_stride; - valarray<size_t> _M_index; // Linear array of referenced indices - _Indexer(size_t, const valarray<size_t>&, - const valarray<size_t>&); - void _M_increment_use() { ++_M_count; } - size_t _M_decrement_use() { return --_M_count; } - }; - - _Indexer* _M_index; - - template<typename _Tp> friend class valarray; - }; - - inline size_t - gslice::start () const - { return _M_index ? _M_index->_M_start : 0; } - - inline valarray<size_t> - gslice::size () const - { return _M_index ? _M_index->_M_size : valarray<size_t>(); } - - inline valarray<size_t> - gslice::stride () const - { return _M_index ? _M_index->_M_stride : valarray<size_t>(); } - - inline gslice::gslice () : _M_index(0) {} - - inline - gslice::gslice(size_t __o, const valarray<size_t>& __l, - const valarray<size_t>& __s) - : _M_index(new gslice::_Indexer(__o, __l, __s)) {} - - inline - gslice::gslice(const gslice& __g) : _M_index(__g._M_index) - { if (_M_index) _M_index->_M_increment_use(); } - - inline - gslice::~gslice() - { if (_M_index && _M_index->_M_decrement_use() == 0) delete _M_index; } - - inline gslice& - gslice::operator= (const gslice& __g) - { - if (__g._M_index) __g._M_index->_M_increment_use(); - if (_M_index && _M_index->_M_decrement_use() == 0) delete _M_index; - _M_index = __g._M_index; - return *this; - } - - -} // std:: - - -#endif /* _GSLICE_H */ - -// Local Variables: -// mode:c++ -// End: |
