从Java代码中Delphi中的线程之间的信号

Question

package org.helioviewer.viewmodel.view.jp2view.concurrency;

/**
 * Very simple way of signaling between threads. Has no sense of ownership and
 * thus any thread can signal or wait for a signal. In general it is not a
 * problem if many different threads call the signal method, but only one thread
 * should be calling the waitForSignal method, since there is no way to tell
 * which thread will be woken up.

public class BooleanSignal {

    /** Signal flag */
    private volatile boolean isSignaled;

    /**
     * Default constructor. Assigns the initial value of the isSignaled flag.
     * 
     * @param _intitialVal
     */
    public BooleanSignal(boolean _intitialVal) {
        isSignaled = _intitialVal;
    }

    /**
     * Used to wait for a signal. Waits until the flag is set, then it resets
     * the flag and returns. The waiting thread can be interrupted and that
     * exception is thrown immediately.
     * 
     * @throws InterruptedException
     */
    public synchronized void waitForSignal() throws InterruptedException {
        while (!isSignaled)
            this.wait();
        isSignaled = false;
    }

    public synchronized void waitForSignal(long timeout) throws InterruptedException {
        while (!isSignaled) {
            this.wait(timeout);
            isSignaled = true;
        }

        isSignaled = false;
    }

    /**
     * Sets the isSignaled flag and wakes up one waiting thread. Doesn't bother
     * to notifyAll since the first thread woken up resets the flag anyway.
     */
    public synchronized void signal() {
        isSignaled = true;
        this.notify();
    }

    /**
     * Returns the signal state.
     * 
     * @return Current signal state
     */
    public synchronized boolean isSignaled() /* throws InterruptedException */{
        /*
         * if(Thread.interrupted()) throw new InterruptedException();
         */
        return isSignaled;
    }
};

我想在使用Delphi的线程之间发信号。我有一个来自Java的示例。如何将此代码转换为Delphi或如何在线程之间发送信号。

我无法直接在另一个线程中调用线程。所以我不知道如何在Delphi中做到这一点？
