Type Members

  1. abstract type CleanUpParam
  2. type FuncType = (Box[T], Boolean) ⇒ Unit

    The function takes a Box[T] (Full if the Var is being set, Empty if it's being cleared) and a Boolean indicating that the set function is setting to the default value.

  3. type ValueType = T

    Perform an atomic update of this Settable. The current value is passed to the function and the ValueHolder is set to the result of the function. This is enclosed in the performAtomicOperation method which will, by default, synchronize this instance

  22. def onChange(f: MyType.FuncType): Unit

    On any change to this Var, invoke the function.

    On any change to this Var, invoke the function. Changes are setting the value, clearing the value. There may not be a call if the Var goes out of scope (e.g., a RequestVar at the end of the Request).

    The function takes a Box[T] (Full if the Var is being set, Empty if it's being cleared) and a Boolean indicating that the set function is setting to the default value.

    The function should execute *very* quickly (e.g., Schedule a function to be executed on a different thread).

    The function should generally be set in Boot or when a singleton is created.

    the function to execute on change
