Modifier and Type	Field and Description
private ThreadGroup	group The thread group either from the security manager or 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).

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.

group

private final ThreadGroup group

The thread group either from the security manager or from the current thread.

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()

Method Detail

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

Specified by:

newThread in interface ThreadFactory
