LazyCell

abstract class LazyCell[A] extends Cell[A]

A cell that evaluates its value on demand. Cell access is unsychronized for performance reasons. However the cell may be safely accessed from multiple threads provided its create method is idempotent.

Abstract Value Members

  1. abstract def create: A

    Create a value.

    Create a value. This method is called when the lazy cell is first accessed. After it is first accessed the value will be cached. There is a chance this method will be called more than once if the cell is accessed from multiple threads.

    Attributes
    protected
  2. abstract def emptyMarker: A

    A value of type A that indicates the cell hasn't been evaluated.

    A value of type A that indicates the cell hasn't been evaluated. Common values are null, None or 0. It's important the marker is not a valid value.
