getThread

public java.lang.Thread getThread(java.lang.Runnable runnable)

Return a Thread which runs the provided Runnable instance. The thread is already started when the method returns.

Specified by:

getThread in interface ThreadFactory

Parameters:

runnable - the Runnable instance that the thread will start to run.

Returns:

a started Thread which runs the provided Runnable instance.

Throws:

java.lang.IllegalArgumentException - when runnable is null.

java.lang.IllegalStateException - when not started.

getName

public java.lang.String getName()

Get the fully qualified name of the instance. Identical to the name used in configure.

configure

public void configure(java.lang.String name,
                      Properties props)
               throws java.lang.Exception

Configure the ThreadFactoryImpl. Currently there are no configuration options defined.

Parameters:

name - the fully qualified instance name.

props - the read-only properties to configure the instance with.

Throws:

java.lang.Exception - when configuration is unsuccessful.

manage

public void manage(Component root,
                   Component parent,
                   java.lang.String operation,
                   java.util.Hashtable parameters)
            throws java.lang.Exception

Manage the ThreadFactoryImpl.

The following management actions are handled:

• LINK. Link the instance with a Jumpi instance.
• STARTUP. Start the instance and allow it to instantiate Threads.
• SHUTDOWN. No action. Threads can still be instantiated after shutdown and before join.
• JOIN. Stop the instance instantiating threads.
• UNLINK. Remove the link to the Jumpi instance.
• INFO. Adds an empty result to the Parameters.INFO_RESULT_SET using the component's fully qualified name as key.
• MANAGE. No operations defined.

Specified by:

manage in interface Manageable

Parameters:

root - the Jumpi instance at the root of the component tree.

parent - the immediate parent of the component.

operation - the operation.

parameters - the operation parameters.

Throws:

java.lang.Exception - if any failure to perform management occurs.

java.lang.IllegalArgumentException - when parameters are missing.
