* <p>V8DebugServer enables debuggers to connect to J2V8 via V8 server sockets debug protocol.
* Server has to be created in the same thread as the provided V8 runtime has been created (the V8 thread).
* You can specify port and whether the {@link #start()} method should
* block until a client connects. {@link #setTraceCommunication(boolean)} allows to output
* communication details for debugging purposes. Before creating V8 runtime you need to set V8 flag to expose
* debug object. If you do not intend to set other flags, than you can use {@link #configureV8ForDebugging()}
* method, otherwise set {@code -expose-debug-as=__j2v8_Debug} flag through {@link V8#setFlags(String)}.
*
* <p>Client connection is handled in a separate thread, however, commands are processed in the V8 thread.
* Therefore it is vital to provide an opportunity to process requests by calling
* {@link #processRequests(long)} method from the V8 thread. This will for instance
* allow to install breakpoints before the JavaScript code starts to execute. It is also good to call that
* method when V8 thread is idle to promptly provide responses to the debugger to avoid timeouts.
*
* <p>Example code:
*
* <code><br>
* &nbsp;&nbsp;//configure for debugging before creating runtime<br>
* &nbsp;&nbsp;V8DebugServer.configureV8ForDebugging();<br>
* <br>
* &nbsp;&nbsp;//create V8 runtime<br>
* &nbsp;&nbsp;V8 runtime = V8.createV8Runtime();<br>
* <br>
* &nbsp;&nbsp;//create and start debug server<br>
* &nbsp;&nbsp;int port = 0;<br>
* &nbsp;&nbsp;boolean waitForConnection = true;<br>
* &nbsp;&nbsp;server = new V8DebugServer(runtime, port, waitForConnection);<br>
* &nbsp;&nbsp;System.out.println("V8 Debug Server listening on port "<br>
* &nbsp;&nbsp;&nbsp;&nbsp;+ server.getPort());<br>
* &nbsp;&nbsp;server.start();<br>

* &nbsp;&nbsp;//execute script and provide name for it<br>
