Class java.util.concurrent.ThreadFactory

Examples of java.util.concurrent.ThreadFactory.newThread()

java.util.concurrent.ThreadFactory.newThread()
Constructs a new {@code Thread}. Implementations may also initialize priority, name, daemon status, {@code ThreadGroup}, etc. @param r a runnable to be executed by new thread instance @return constructed thread, or {@code null} if the request tocreate a thread is rejected

        ThreadFactory wrapped = EasyMock.createMock(ThreadFactory.class);
        Runnable r = EasyMock.createMock(Runnable.class);
        final int orgPriority = Thread.NORM_PRIORITY + 1;
        Thread t = new Thread();
        t.setPriority(orgPriority);
        EasyMock.expect(wrapped.newThread(r)).andReturn(t);
        EasyMock.replay(wrapped, r);
        BasicThreadFactory factory = builder.wrappedFactory(wrapped).build();
        assertSame("Wrong thread", t, factory.newThread(r));
        assertEquals("Wrong priority", orgPriority, t.getPriority());
