Java Utililty Methods Thread Executor Create

ThreadFactory createDaemonThreadFactory()
Creates a ThreadFactory which produces threads which run as daemons.

return createDaemonThreadFactory(null);

ThreadPoolExecutor createDefaultExecutorService()
Returns a new thread pool configured with the default settings.

ThreadFactory threadFactory = new ThreadFactory() {
 private int threadCount = 1;
 public Thread newThread(Runnable r) {
 Thread thread = new Thread(r);
 thread.setName("s3-transfer-manager-worker-" + threadCount++);
 return thread;
};
...

ThreadPoolExecutor createDefaultExecutorService(final String threadNamePrefix, final int parallel)
Returns a new thread pool configured with the default settings.

ThreadFactory threadFactory = new ThreadFactory() {
 private int threadCount = 1;
 public Thread newThread(Runnable r) {
 Thread thread = new Thread(r);
 thread.setName(threadNamePrefix + threadCount++);
 return thread;
};
...

ExecutorService createEventsOrderedDeliveryExecutor()
create Events Ordered Delivery Executor

return Executors.newSingleThreadExecutor(new ThreadFactory() {
 private AtomicInteger cnt = new AtomicInteger(0);
 @Override
 public Thread newThread(Runnable r) {
 Thread t = new Thread(r, "Ordered Events Thread-" + cnt.incrementAndGet());
 t.setDaemon(true);
 return t;
});

ScheduledExecutorService createExecutor()
create Executor

return Executors.newSingleThreadScheduledExecutor(daemonThreadFactory());

ExecutorService createExecutor(final String file)
create Executor

return Executors.newSingleThreadExecutor(new ThreadFactory() {
 public Thread newThread(Runnable r) {
 return new Thread(r, "Export thread for " + file); 
});

ExecutorService createExecutors(int numThreads)
create Executors

return Executors.newFixedThreadPool(numThreads, new ThreadFactory() {
 public Thread newThread(Runnable r) {
 Thread thread = new Thread(r);
 thread.setName(r.getClass().getName());
 return thread;
});

ThreadPoolExecutor createExecutorService()
create Executor Service

return new ThreadPoolExecutor(1, 1, 60L, TimeUnit.SECONDS, new LinkedBlockingQueue<Runnable>());

ScheduledExecutorService createResourceRetrievalService(final String threadName)
Convenience method to create a java.util.concurrent.ScheduledExecutorService which can be used by World Wind components to schedule periodic resource checks.

ThreadFactory threadFactory = new ThreadFactory() {
 public Thread newThread(Runnable r) {
 Thread thread = new Thread(r);
 thread.setDaemon(true);
 thread.setPriority(Thread.MIN_PRIORITY);
 if (threadName != null) {
 thread.setName(threadName);
 return thread;
};
return Executors.newSingleThreadScheduledExecutor(threadFactory);

ExecutorService createSingleThreadExecutor(final String name)
create Single Thread Executor

return Executors.newSingleThreadExecutor(createSimpleThreadFactory(name));
