nonCellGridRange

function nonCellGridRange(gridRange: GridRange): boolean;

nonCellGridRange(value) is the same test as !isCellGridRange(value), written so that a guard clause reads as a sentence rather than as a negation.

One row and one column, measured by the bounds rather than by how the range was written: the end indices are exclusive, so a single cell is endRowIndex - startRowIndex === 1 and the same for the columns. A range with a bound left out is open in that direction and is never a single cell.

isX and nonX answer a question and never interrupt control flow; requireX and requireNonX hand the value back or throw. The scheme is explained in Validation conventions.

Parameters

Parameter	Type	Description
`gridRange`	`GridRange`	The grid range to check.

Returns

boolean — true when the value is not a single-cell range; otherwise false.

Examples

What passes and what does not

nonCellGridRange({ startRowIndex: 0, endRowIndex: 2, startColumnIndex: 0, endColumnIndex: 1 }); // => true
nonCellGridRange({}); // => true
nonCellGridRange(null); // => true
nonCellGridRange({ startRowIndex: 0, endRowIndex: 1, startColumnIndex: 0, endColumnIndex: 1 }); // => false
