Selection class abstract
The most simple description of a portion of the grid that is supposed to be selected or to receive a special decoration (defined by style).
Bottom and right values are non-inclusive, this means that a selection with a bottom value of 14 includes up to the row with index 13.
Each side of the regularly rectangle-shaped region can receive a null value, This mens that the selection ahs no clear bound (unbounded) for that size, deferring the boundaries to the size of the table.
For example, a selection with the following side values:
- left: 4
- top: 2
- right: null
- bottom 4
That selection will include all cells in the rows 2 and 3 and in the columns starting from 4 until the end of the table to the right.
A table with both top and bottom values set to null will include entire columns. The same applies to left and right selecting entire rows.
A table with all side values set to null will include all cells of a table.
Side values are assumed to be normalized, then subclasses should make sure that these conditions are always true:
- top <= bottom
- left <= right
