Constructor Detail

CustomizableThreadCreator

public CustomizableThreadCreator()

Create a new CustomizableThreadCreator with default thread name prefix.

CustomizableThreadCreator

public CustomizableThreadCreator(java.lang.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

setThreadNamePrefix

public void setThreadNamePrefix(java.lang.String threadNamePrefix)

Specify the prefix to use for the names of newly created threads. Default is "SimpleAsyncTaskExecutor-".

getThreadNamePrefix

public java.lang.String getThreadNamePrefix()

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

setThreadPriority

public void setThreadPriority(int threadPriority)

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

See Also:

Thread.NORM_PRIORITY

getThreadPriority

public int getThreadPriority()

Return the priority of the threads that this factory creates.

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.

See Also:

Thread.setDaemon(boolean)

isDaemon

public boolean isDaemon()

Return whether this factory should create daemon threads.

setThreadGroupName

public void setThreadGroupName(java.lang.String name)

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

See Also:

setThreadGroup(java.lang.ThreadGroup)

setThreadGroup

public void setThreadGroup(java.lang.ThreadGroup threadGroup)

Specify the thread group that threads should be created in.

See Also:

setThreadGroupName(java.lang.String)

getThreadGroup

public java.lang.ThreadGroup getThreadGroup()

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

createThread

public java.lang.Thread createThread(java.lang.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

See Also:

nextThreadName()

nextThreadName

protected java.lang.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".

See Also:

getThreadNamePrefix()

getDefaultThreadNamePrefix

protected java.lang.String getDefaultThreadNamePrefix()

Build the default thread name prefix for this factory.

Returns:

the default thread name prefix (never null)
