com.google.common.util.concurrent.ThreadFactoryBuilder
A ThreadFactory builder, providing any combination of these features:
- whether threads should be marked as {@linkplain Thread#setDaemon daemon}threads
- a {@linkplain ThreadFactoryBuilder#setNameFormat naming format}
- a {@linkplain Thread#setPriority thread priority}
- an {@linkplain Thread#setUncaughtExceptionHandler uncaught exceptionhandler}
- a {@linkplain ThreadFactory#newThread backing thread factory}
If no backing thread factory is provided, a default backing thread factory is used as if by calling {@code setThreadFactory(}{@link Executors#defaultThreadFactory()}{@code )}. @author Kurt Alfred Kluever @since Guava release 04
