Class ActivationGroupDesc

public final class ActivationGroupDesc extends Object implements Serializable

Contains information, necessary to create of recreate the activation objects. The group descriptor contains:

The name of the group's class. This class is derived from the {@link ActivationGroup}.
The group class code location.
The marshalled object that contains the group specific initialization information

The groups are created by the {@link ActivationGroup#createGroup} method that expectes the group class to have the two parameter constructor, the first parameter being the {@link ActivationGroupID} and the second the {@link MarshalledObject}.

Nested Class Summary
static class	ActivationGroupDesc.CommandEnvironment Contains the startup options for the {@link ActivationGroup} implementations.

Constructor Summary
	ActivationGroupDesc(Properties aProperties, ActivationGroupDesc.CommandEnvironment environment) Create the new activation group descriptor that will use the default activation group implementation with the given properties and environment.
	ActivationGroupDesc(String aClassName, String aLocation, MarshalledObject aData, Properties aProperties, ActivationGroupDesc.CommandEnvironment environment) Create the new activation group descriptor.

Method Summary
boolean	equals(Object obj) Compare for the content equality.
String	getClassName() Get the activation group class name.
ActivationGroupDesc.CommandEnvironment	getCommandEnvironment() Get the group command environment, containing path to the jre executable and startup options.
MarshalledObject	getData() Get the group intialization data.
String	getLocation() Get the location, from where the group class will be loaded
Properties	getPropertyOverrides() Get the overridded system properties.
int	hashCode() Return the hashcode.

Constructor Detail

ActivationGroupDesc

public ActivationGroupDesc(Properties aProperties, ActivationGroupDesc.CommandEnvironment environment)

Create the new activation group descriptor that will use the default activation group implementation with the given properties and environment.

Parameters: aProperties the properties that override the system properties environment the command line (and parameters), indicating, where to find the jre executable and with that parameters to call it. May be null if the default executable should be used. In this case, the activation group with the null name (the system default group) will be created.

ActivationGroupDesc

public ActivationGroupDesc(String aClassName, String aLocation, MarshalledObject aData, Properties aProperties, ActivationGroupDesc.CommandEnvironment environment)

Create the new activation group descriptor.

Parameters: aClassName the name of the group implementation class. The null value indicates the default implementation. aLocation the location, from where the group implementation class should be loaded (ignored for the system default implementation). aData the group intialization data aProperties the properties that will override the system properties of the new group. These properties will be translated into -D options. environment the record, containing path to the jre executable and start options for the jre or null for using the default jre and options.
