public void createExecutor() {
internalExecutor = true;
TaskQueue taskqueue = new TaskQueue();
TaskThreadFactory tf = new TaskThreadFactory(getName() + "-exec-", daemon, getThreadPriority());

}
TaskThreadFactory这个类的源码如下:
public class TaskThreadFactory implements ThreadFactory {
private final ThreadGroup group;
private final AtomicInteger threadNumber = new AtomicInteger(1);
private final String namePrefix;
private final boolean daemon;
private final int threadPriority;
public TaskThreadFactory(String namePrefix, boolean daemon, int priority) {
SecurityManager s = System.getSecurityManager();
group = (s != null) ? s.getThreadGroup() : Thread.currentThread().getThreadGroup();
this.namePrefix = namePrefix;
this.daemon = daemon;
this.threadPriority = priority;
}
@Override
public Thread newThread(Runnable r) {
TaskThread t = new TaskThread(group, r, namePrefix + threadNumber.getAndIncrement());
t.setDaemon(daemon);
t.setPriority(threadPriority);
return t;
}
}
