Py4J Java API ============= The Java API is under active development and will be refactored in the next releases. You can browse the `javadoc <_static/javadoc/index.html>`_, but most classes are not documented yet. For now, the best way to use the API is to: 1. Create a class that extends the `DefaultGateway <_static/javadoc/index.html?py4j/DefaultGateway.html>`_. 2. Initialize a `GatewayServer <_static/javadoc/index.html?py4j/GatewayServer.html>`_ with your newly created class. 3. Call the `Gateway.start() <_static/javadoc/py4j/GatewayServer.html#start(boolean)>`_ method to enable your Python program to access your gateway.
