public class: ActivationGroupID [javadoc | source]

java.lang.Object
   java.rmi.activation.ActivationGroupID

All Implemented Interfaces:
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.

Methods from java.lang.Object:
clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait

Method from java.rmi.activation.ActivationGroupID Detail:
public boolean equals(Object obj) { if (this == obj) { return true; } else if (obj instanceof ActivationGroupID) { ActivationGroupID id = (ActivationGroupID)obj; return (uid.equals(id.uid) && system.equals(id.system)); } else { return false; } } 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.
public ActivationSystem getSystem() { return system; } Returns the group's activation system.
public int hashCode() { return uid.hashCode(); } Returns a hashcode for the group's identifier. Two group identifiers that refer to the same remote group will have the same hash code.

 public boolean equals(Object obj) {
        if (this == obj) {
            return true;
        } else if (obj instanceof ActivationGroupID) {
            ActivationGroupID id = (ActivationGroupID)obj;

        } else {
            return false;
        }
}

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.

 public ActivationSystem getSystem() {
        return system;
}

Returns the group's activation system.

 public int hashCode() {
        return uid.hashCode();
}

Returns a hashcode for the group's identifier. Two group identifiers that refer to the same remote group will have the same hash code.
