  • ActivationGroupDesc

    public ActivationGroupDesc(Properties overrides,
     ActivationGroupDesc.CommandEnvironment cmd)

    Constructs a group descriptor that uses the system defaults for group implementation and code location. Properties specify Java environment overrides (which will override system properties in the group implementation's VM). The command environment can control the exact command/options used in starting the child VM, or can be null to accept rmid's default.

    This constructor will create an ActivationGroupDesc with a null group class name, which indicates the system's default ActivationGroup implementation.

    Parameters:

    overrides - the set of properties to set when the group is recreated.

    cmd - the controlling options for executing the VM in another process (or null).

    Since:

    1.2

  • ActivationGroupDesc

    public ActivationGroupDesc(String className,
     String location,
     MarshalledObject<?> data,
     Properties overrides,
     ActivationGroupDesc.CommandEnvironment cmd)

    Specifies an alternate group implementation and execution environment to be used for the group.

    Parameters:

    className - the group's package qualified class name or null. A null group class name indicates the system's default ActivationGroup implementation.

    location - the location from where to load the group's class

    data - the group's initialization data contained in marshalled form (could contain properties, for example)

    overrides - a properties map which will override those set by default in the subprocess environment (will be translated into -D options), or null.

    cmd - the controlling options for executing the VM in another process (or null).

    public Properties getPropertyOverrides()

    Returns the group's property-override list.

    Returns:

    the property-override list, or null

    Since:

    1.2

  • getCommandEnvironment

    public ActivationGroupDesc.CommandEnvironment getCommandEnvironment()

    Returns the group's command-environment control object.

    Returns:

    the command-environment object, or null

    Since:

  • equals

    public boolean equals(Object obj)

    Compares two activation group descriptors for content equality.

    Overrides:

    equals in class Object

    Parameters:

    obj - the Object to compare with

    Returns:

    true if these Objects are equal; false otherwise.
