Constructor Detail

CustomizableThreadFactory

public CustomizableThreadFactory(String threadNamePrefix)

Create a new CustomizableThreadCreator with the given thread name prefix.

Parameters:

threadNamePrefix - the prefix to use for the names of newly created threads

Method Detail

newThread

public Thread newThread(Runnable runnable)

Specified by:

newThread in interface ThreadFactory

getThreadNamePrefix

public String getThreadNamePrefix()

Return the thread name prefix to use for the names of newly created threads.

Returns:

the thread name prefix

setThreadPriority

public void setThreadPriority(int threadPriority)

Set the priority of the threads that this factory creates. Default is 5.

Parameters:

threadPriority - the thread priority

See Also:

Thread#NORM_PRIORITY

getThreadPriority

public int getThreadPriority()

Return the priority of the threads that this factory creates.

Returns:

the thread priority

setDaemon

public void setDaemon(boolean daemon)

Set whether this factory is supposed to create daemon threads, just executing as long as the application itself is running.

Default is "false": Concrete factories usually support explicit cancelling. Hence, if the application shuts down, Runnables will by default finish their execution.

Specify "true" for eager shutdown of threads which still actively execute a Runnable at the time that the application itself shuts down.

Parameters:

daemon - the daemon

See Also:

Thread#setDaemon

isDaemon

public boolean isDaemon()

Return whether this factory should create daemon threads.

Returns:

the boolean

setThreadGroupName

public void setThreadGroupName(String name)

Specify the name of the thread group that threads should be created in.

Parameters:

name - the name

See Also:

#setThreadGroup

setThreadGroup

public void setThreadGroup(ThreadGroup threadGroup)

Specify the thread group that threads should be created in.

Parameters:

threadGroup - the thread group

See Also:

#setThreadGroupName

getThreadGroup

public ThreadGroup getThreadGroup()

Return the thread group that threads should be created in (or null for the default group).

Returns:

the thread group

createThread

public Thread createThread(Runnable runnable)

Template method for the creation of a new Thread.

The default implementation creates a new Thread for the given Runnable, applying an appropriate thread name.

Parameters:

runnable - the Runnable to execute

Returns:

the thread

See Also:

#nextThreadName()

nextThreadName

protected String nextThreadName()

Return the thread name to use for a newly created Thread.

The default implementation returns the specified thread name prefix with an increasing thread count appended: e.g. "SimpleAsyncTaskExecutor-0".

Returns:

the string
