java.lang.Object
  com.google.common.util.concurrent.ThreadFactoryBuilder

public final class ThreadFactoryBuilder
extends Object

A ThreadFactory builder, providing any combination of these features:

• whether threads should be marked as daemon threads
• a naming format
• a thread priority
• an uncaught exception handler
• a backing thread factory

If no backing thread factory is provided, a default backing thread factory is used as if by calling setThreadFactory(Executors.defaultThreadFactory()).

4.0

public ThreadFactoryBuilder()

Creates a new ThreadFactory builder.

Method Detail

setNameFormat

public ThreadFactoryBuilder setNameFormat(String nameFormat)

Sets the naming format to use when naming threads (Thread.setName(java.lang.String)) which are created with this ThreadFactory.

Parameters:

nameFormat - a String.format(String, Object...)-compatible format String, to which a unique integer (0, 1, etc.) will be supplied as the single parameter. This integer will be unique to the built instance of the ThreadFactory and will be assigned sequentially.

Returns:

this for the builder pattern

setDaemon

public ThreadFactoryBuilder setDaemon(boolean daemon)

Sets daemon or not for new threads created with this ThreadFactory.

Parameters:

daemon - whether or not new Threads created with this ThreadFactory will be daemon threads

Returns:

this for the builder pattern

setPriority

public ThreadFactoryBuilder setPriority(int priority)

Sets the priority for new threads created with this ThreadFactory.

Parameters:

priority - the priority for new Threads created with this ThreadFactory

Returns:

this for the builder pattern

setUncaughtExceptionHandler

public ThreadFactoryBuilder setUncaughtExceptionHandler(Thread.UncaughtExceptionHandler uncaughtExceptionHandler)

Sets the Thread.UncaughtExceptionHandler for new threads created with this ThreadFactory.

Parameters:

uncaughtExceptionHandler - the uncaught exception handler for new Threads created with this ThreadFactory

Returns:

this for the builder pattern

setThreadFactory

public ThreadFactoryBuilder setThreadFactory(ThreadFactory backingThreadFactory)

Sets the backing ThreadFactory for new threads created with this ThreadFactory. Threads will be created by invoking #newThread(Runnable) on this backing ThreadFactory.

Parameters:

backingThreadFactory - the backing ThreadFactory which will be delegated to during thread creation.

Returns:

this for the builder pattern

build

public ThreadFactory build()

Returns a new thread factory using the options supplied during the building process. After building, it is still possible to change the options used to build the ThreadFactory and/or build again. State is not shared amongst built instances.

Returns:

the fully constructed ThreadFactory
