Type Members

  1. abstract type G

    Internal state type used to describe a set of tasks.

Abstract Value Members

  1. abstract def add(g: G, a: A): G

    Updates the description g to include a new task a.

  2. abstract def empty: G

    Representation of zero tasks.

  3. abstract def remove(g: G, a: A): G

    Updates the description g to remove a previously added task a.

  4. abstract def valid(g: G): Boolean

    Returns true if the tasks described by g are allowed to execute concurrently.

    Returns true if the tasks described by g are allowed to execute concurrently. The methods in this class must obey the following laws:

    1. forall g: G, a: A; valid(g) => valid(remove(g,a)) 2. forall a: A; valid(add(empty, a)) 3. forall g: G, a: A; valid(g) <=> valid(remove(add(g, a), a)) 4. (implied by 1,2,3) valid(empty) 5. forall g: G, a: A, b: A; !valid(add(g,a)) => !valid(add(add(g,b), a))
