Python Factory.numConnect方法代码示例

# 需要导入模块: from twisted.internet.protocol import Factory [as 别名]
# 或者: from twisted.internet.protocol.Factory import numConnect [as 别名]
def serve_tcp(engine=None, port=8007, logto=sys.stdout, max_connect=1):
    """Serve the `M2TCP` protocol using the given `engine` on the
    specified `port` logging messages to given `logto` which is a
    file-like object.  This function will block till the service is
    closed.  There is no need to call `mlab.show()` after or before
    this.  The Mayavi UI will be fully responsive.

    **Parameters**

     :engine: Mayavi engine to use. If this is `None`,
              `mlab.get_engine()` is used to find an appropriate engine.

     :port: int: port to serve on.

     :logto: file: File like object to log messages to.  If this is
                   `None` it disables logging.

     :max_connect: int: Maximum number of simultaneous connections to
                        support.

    **Examples**

    Here is a very simple example::

        from mayavi import mlab
        from mayavi.tools import server
        mlab.test_plot3d()
        server.serve_tcp()

    The TCP server will listen on port 8007 by default in the above.
    Any data sent to the server is simply exec'd, meaning you can do
    pretty much anything you want.  The `engine`, `scene`, `camera` and
    `mlab` are all available and can be used.  For example after running
    the above you can do this::

        $ telnet localhost 8007
        Trying 127.0.0.1...
        Connected to localhost.
        Escape character is '^]'.
        scene.camera.azimuth(45)
        mlab.clf()
        mlab.test_contour3d()
        scene.camera.zoom(1.5)

    **Warning**

    Data sent is exec'd so this is a security hole.
