Field Summary

Fields

Modifier and Type	Field	Description
private ThreadGroup	group	The thread group from the security manager if it exists or else from the current thread.
private String	namePrefix	The name prefix of the form <threadname>-javaoctave-<prefix>-<POOLNUMBER>-, where <threadname> is the name of the current thread, <prefix> is the prefix given by a parameter of the constructor NamedThreadFactory(String) and <POOLNUMBER> is POOL_NUMBER depending on the factory object.
private static AtomicInteger	POOL_NUMBER	This is initialized with 1 and read and incremented only if a factory object is created.
private AtomicInteger	threadNumber	The number of the thread created next by this factory starting with one and being incremented by method newThread(Runnable).

Constructor Summary

Constructors

Modifier	Constructor	Description
	NamedThreadFactory()	Creates a NamedThreadFactory via NamedThreadFactory(String) with name given by the simple class name of OctaveExec.
private	NamedThreadFactory(String prefix)	Will create a factory that create Threads with the names: [parent]-javaoctave-[prefix]-[pool#]-[thread#].

Method Summary

Modifier and Type	Method	Description
Thread	newThread(Runnable runnable)	Returns a new thread with standard priority which is no daemon with default priority Thread.NORM_PRIORITY from runnable with name consisting of namePrefix and a running number threadNumber.

Field Detail

POOL_NUMBER

private static final AtomicInteger POOL_NUMBER

This is initialized with 1 and read and incremented only if a factory object is created. It goes into namePrefix.

group

private final ThreadGroup group

The thread group from the security manager if it exists or else from the current thread. It is the group each thread belongs to created by newThread(Runnable).

namePrefix

private final String namePrefix

The name prefix of the form <threadname>-javaoctave-<prefix>-<POOLNUMBER>-, where <threadname> is the name of the current thread, <prefix> is the prefix given by a parameter of the constructor NamedThreadFactory(String) and <POOLNUMBER> is POOL_NUMBER depending on the factory object. The trailing - is there because a new thread defined by newThread(Runnable) obtains a name consisting of the prefix followed by threadNumber.

threadNumber

private final AtomicInteger threadNumber

The number of the thread created next by this factory starting with one and being incremented by method newThread(Runnable).

Constructor Detail

NamedThreadFactory

private NamedThreadFactory(String prefix)

Will create a factory that create Threads with the names: [parent]-javaoctave-[prefix]-[pool#]-[thread#]. Here, [parent] is the name of the parent thread, i.e. of the current thread, [prefix] is given by the parameter [pool#] is the number of this factory and [thread#] refers to the number of the thread created by this factory.

Parameters:

prefix -

NamedThreadFactory

public NamedThreadFactory()

Creates a NamedThreadFactory via NamedThreadFactory(String) with name given by the simple class name of OctaveExec.

Method Detail

newThread

public Thread newThread(Runnable runnable)

Returns a new thread with standard priority which is no daemon with default priority Thread.NORM_PRIORITY from runnable with name consisting of namePrefix and a running number threadNumber.

Specified by:

newThread in interface ThreadFactory

Parameters:

runnable - the runnable to create a thread from.
