ActivationGroupDesc JDK 1.6)

Description

publicfinal class ActivationGroupDesc

An activation group descriptor contains the information necessary to create/recreate an activation group in which to activate objects.

See also: ActivationGroup ActivationGroupID

Constructors

public ActivationGroupDesc (Properties overrides, CommandEnvironment cmd)

Constructs a group descriptor that uses the system defaults for group implementation and code location.

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

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

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

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).
Since: 1.2
