Class java.rmi.activation.ActivationGroupDesc

java.lang.Object
    |
    +----java.rmi.activation.ActivationGroupDesc

public final class ActivationGroupDesc

extends Object

implements Serializable

• the group's class name,
• the group's code source (the location of the group's class), and
• a "marshalled" object that can contain object specific initialization data.

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:

• the group's ActivationGroupID, and
• the group's initialization data (in a java.rmi.MarshalledObject)

Since:

JDK1.2

See Also:

ActivationGroup, ActivationGroupID

ActivationGroupDesc(Properties)

Constructs a group descriptor that uses system default for group implementation and code source.

ActivationGroupDesc(String, CodeSource, MarshalledObject)

Specifies an alternate group implementation to be used for the group.

getClassName()

Returns the group's class name.

getCodeSource()

Returns the group's code source.

getData()

Returns the group's initialization data.

public ActivationGroupDesc(Properties properties) throws IOException

Constructs a group descriptor that uses system default for group implementation and code source. Properties specify environment. The additional property java.rmi.activation.security.class and java.rmi.activation.security.codebase specifies (respectively) the class name of the security manager, and the codebase, the location, of the class. If former property is not set, then the java.rmi.RMISecurityManager will be used as the security manager for group.

Parameters:

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

Throws: NullPointerException

if properties is null

Throws: IOException

if a MarshalledObject could not be created from the properties

public ActivationGroupDesc(String className,
                           CodeSource source,
                           MarshalledObject data)

Specifies an alternate group implementation to be used for the group.

Parameters:

className - the group's fully package qualified className

source - the CodeSource from where to load the group's class

data - the group's initialization data contained in marshalled form.

public String getClassName()

Returns the group's class name.

Returns:

the group's class name

public CodeSource getCodeSource()

Returns the group's code source.

Returns:

the group's code source

public MarshalledObject getData()

Returns the group's initialization data.

Returns:

the group's initialization data
