Methods

addObserver(CellObserver observer) → void
Register an observer of the cell to be called when the cell's value changes.
inherited
call() → T
Retrieve the value of the cell.
inherited
eq<U>(ValueCell<U> other) → ValueCell<bool>
Returns a new ValueCell which compares the value of this cell to another cell for equality.
inherited
neq<U>(ValueCell<U> other) → ValueCell<bool>
Returns a new ValueCell which compares the value of this cell to another cell for inequality.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
observe() → void
Track this cell as an argument of the current compute/watch function.
inherited
removeObserver(CellObserver observer) → void
Remove an observer that was previously registered with addObserver.
inherited
toString() → String
