A Python to Java bridge (ctypes/cffi-based PyJava).

Project description

jtypes.pyjava

A Python to Java bridge.

Overview

jtypes.pyjava is a bridge allowing to use Java classes in regular Python code.

PyPI record.

Documentation.

jtypes.pyjava is an almost fully compliant implementation of Remi Rampin’s PyJava package by reimplementing whole its functionality in a clean Python instead of C.
jtypes.pyjava package is closely based on the jvm and jni Python packages.

About PyJava:

Borrowed from the original website:

PyJava is a bridge allowing to use Java classes in regular Python code.
It is similar to JPype.

It is a C extension that uses JNI to access a Java virtual machine, meaning that it can be used anywhere Python is available. It is not a different interpreter like Jython and does not require anything, other than a JRE. The JVM dynamic library is load dynamically through pyjava.start() (some basic logic for locating this library on major platforms will be provided).

The integration with Java code is meant to be as complete as possible, allowing to use Java and Python objects seemlessly and converting objects back and forth when Java code is called. Furthermore, subclassing Java classes or interfaces in Python code to allow callback from Java is planned for the 0.2 version.

Please note that this extension is still at a very early stage of development and probably shouldn’t be used for anything.

Requirements
