Class ActivationGroupID

  • All Implemented Interfaces:
    Serializable
    public class ActivationGroupID
extends Object
implements Serializable
    The identifier for a registered activation group serves several purposes:
    • identifies the group uniquely within the activation system, and
    • contains a reference to the group's activation system so that the group can contact its activation system when necessary.

    The ActivationGroupID is returned from the call to ActivationSystem.registerGroup and is used to identify the group within the activation system. This group id is passed as one of the arguments to the activation group's special constructor when an activation group is created/recreated.

      • hashCode

      • equals

        public boolean equals​(Object obj)
        Compares two group identifiers for content equality. Returns true if both of the following conditions are true: 1) the unique identifiers are equivalent (by content), and 2) the activation system specified in each refers to the same remote object.
        Overrides:
        equals in class Object
        Parameters:
        obj - the Object to compare with
        Returns:
        true if these Objects are equal; false otherwise.
