Cell

trait Cell[T] extends Dependent

A wiring Cell. A Cell can be a ValueCell which holds a value which can be set (and thus update the dependencies), a FuncCell (a cell that is a function that depends on other cells), or a DynamicCell which has a value that updates each time the cell is accessed.

Abstract Value Members

  1. abstract def currentValue: (T, Long)

    The cell's value and most recent change time

  2. abstract def predicateChanged(which: Cell[_]): Unit

    If the predicate cell changes, the Dependent will be notified

    If the predicate cell changes, the Dependent will be notified
