Divider

Identifies a divider originating from a corner of a cell and going to an adjacent corner. The coordinates:

• are zero-based
• do NOT depend on the grid's orientation
• do depend on the layout orientation The set of coordinates in a grid identifies the intersections in a grid between two lines. The divider is always directing towards a greater coordinate value. For example: if a divider has an originX of 1, a originY of 2 and it's horizontal, it means that divider is the line between the points (x)1;(y)2 and (x)2;(y)2.

Some examples of a list with 3 items:

left-to-right        right-to-left        left-to-right        right-to-left

The set of coordinates is NOT a projection of the intersections of all the lines in a grid N (rows) x M (columns), but they map exactly the given grid, considering the cells' spans. The coordinates match their projection only when all the items have a span size of 1. This decision was taken only to simplify the customization of a single divider with the different providers, even if it's less coherent with the structure of a standard table.

An example of a grid with 4 items having different span sizes:

              top-to-bottom
              left-to-right

    0;0 ----> 1;0 --------------> 2;0
     |         |                   |
     |    0    |         1         |
     ∨         ∨                   ∨
    0;1 ----> 1;1 ----> 1;1 ----> 2;1
     |                   |         |
     |         2         |    3    |
     ∨                   ∨         ∨
    0;2 --------------> 1;2 ----> 2;2

The coordinate (x)1;(y)1 is repeated twice since it's the bottom divider of the item with index 0 and the top divider of the item with index 2.

Parameters

grid - the grid in which this divider should appear.

originX - the x-coordinate from which the divider is originating.

originY - the y-coordinate from which the divider is originating.

orientation - Orientation.HORIZONTAL if the divider is horizontal, Orientation.VERTICAL if the divider is vertical.
