ActorGC

trait ActorGC extends TerminationMonitor

ActorGC keeps track of the number of live actors being managed by a a scheduler so that it can shutdown when all of the actors it manages have either been explicitly terminated or garbage collected.

When an actor is started, it is registered with the ActorGC via the newActor method, and when an actor is knowingly terminated (e.g. act method finishes, exit explicitly called, an exception is thrown), the ActorGC is informed via the terminated method.

  2. def equals(arg0: Any): Boolean

    This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence

    This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.

    The default implementations of this method is an equivalence relation:

    • It is reflexive: for any instance x of type Any, x.equals(x) should return true.
    • It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
    • It is transitive: for any instances x, y, and z of type AnyRef if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

    If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is often necessary to override hashCode to ensure that objects that are "equal" (o1.equals(o2) returns true) hash to the same Int (o1.hashCode.equals(o2.hashCode)).

    arg0

    the object to compare against this object for equality.

    returns

    true if the receiver object is equivalent to the argument; false otherwise.

  3. def hashCode(): Int

    Returns a hash code value for the object

    Returns a hash code value for the object.

    The default hashing algorithm is platform dependent.

    Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

    newActor is invoked whenever a new actor is started.

  5. def onTerminate(a: Reactor)(f: ⇒ Unit): Unit

    Registers a closure to be executed when the specified actor terminates

    Registers a closure to be executed when the specified actor terminates.

  6. def terminated(a: Reactor): Unit

    Registers that the specified actor has terminated

    Registers that the specified actor has terminated.

    a

    the actor that has terminated

  7. def toString(): String

    Returns a string representation of the object

    Returns a string representation of the object.
