Py4J Python API
===============

Using Py4J is usually as simple as creating a :ref:`JavaGateway <api_javagateway>` object:

::

  java_gateway = JavaGateway()
  # you are now connected to the JVM
  # and you can call any method defined on the Java side.

You can still customize and extend Py4J in many ways (e.g., you can choose the
port to which you want to connect). The following modules are documented. Note
that users are expected to only use :mod:`py4j.java_gateway` or
:mod:`py4j.clientserver`.
