none static method
dynamic
none([
- dynamic defaultValue
Stop computation of the current cell's value.
When this method is called within a cell's value computation function, the cell's value is not recomputed. Instead the cell's current value is preserved.
If this method is called when a cell's initial value is being computed,
the cell's initial value is set to defaultValue
.
If defaultValue
is null, and this method is used during the computation
of the initial value of a cell with a value type that is not nullable,
an UninitializedCellError
is thrown.
Implementation
static none([defaultValue]) => throw StopComputeException(defaultValue);
