This class is able to store the frame styles of an array of cells and to draw the entire array or parts of it to any output device. Every cell contains the style of the left, right, top, bottom, top-left to bottom-right, and bottom-left to top-right frame border. On drawing, the thicker frame border of neighbored cells is selected automatically. All borders are drawn "connected", that means, the correct start and end coordinates of all lines of the borders are calculated, especially, if they are drawn together with diagonal frame borders. This array fully supports merged cell ranges. In a merged range, the frame borders of the top-left cell is extended to the entire range, and all other cells in that range are overlapped. Again, all connected frame borders, also diagonals and frame borders from adjacent merged ranges, are handled automatically. Additionally, a clipping range can be set. If such a range is used, all frame borders outside this range are completely ignored, and are not used in the connected border calculation anymore. The array can be mirrored in both directions. It is possible to specify, whether to mirror the double frame styles, and whether to swap diagonal frame borders. */ class SAL_WARN_UNUSED SVXCORE_DLLPUBLIC Array { public: /** Constructs an empty array. */ explicit Array(); /** Destructs the array. */ ~Array(); // array size and column/row indexes /** Reinitializes the array with the specified size.
