java.lang.Object | +--java.rmi.activation.ActivationGroupDesc
An activation group descriptor contains the information necessary to create/recreate an activation group in which to activate objects. Such a descriptor contains:
The group's class must be a concrete subclass of
ActivationGroup
. A subclass of
ActivationGroup
is created/recreated via the
ActivationGroup.createGroup
static method that invokes
a special constructor that takes two arguments:
ActivationGroupID
, and
java.rmi.MarshalledObject

Constructor Detail |
public ActivationGroupDesc(Properties overrides, ActivationGroupDesc.CommandEnvironment cmd)
java.rmi.activation.security.class
and
java.rmi.activation.security.codebase
specify
(respectively) the class name of the security manager, and the
codebase (the location) of the class. If the former property is
not set, then the java.rmi.RMISecurityManager
will
be used as the security manager for the group. The command
environment can control the exact command/options used in
starting the child VM, or can be null
to accept
rmid's default.properties
- the set of properties to set when the group is
recreated.cmd
- the controlling options for executing the VM in
another process (or null).public ActivationGroupDesc(String className, String location, MarshalledObject data, Properties overrides, ActivationGroupDesc.CommandEnvironment cmd)
className
- the group's fully package qualified classNamelocation
- the location from where to load the group's

- the group's initialization data contained in
marshalled form (could contain properties, for example)overrides
- a properties map which will override those set

into -D
