Dynamic access to Java classes from Python (ctypes/cffi-based PyJNIus)

Project description

Currently only as placeholder (because a base package jtypes.jvm is still in development)

jtypes.pyjnius

Dynamic access to Java classes from Python.

Overview

jtypes.pyjnius is a bridge between Python and Java, allowing these to intercommunicate.
It is an effort to allow python programs full access to Java class libraries.

PyPI record.

jtypes.pyjnius is a lightweight Python package, based on the ctypes or cffi library.
It is an almost fully compliant implementation of Kivy Team’s PyJNIus package by reimplementing whole its functionality in a clean Python instead of Cython.

About PyJNIus:

Borrowed from the original website:

PyJNIus is a Python library for accessing Java classes.

A minimal PyJNIus example looks something like this:

Quick overview

>>> from jnius import autoclass
>>> System = autoclass('java.lang.System')
>>> System.out.println('Hello world')
Hello world

>>> Stack = autoclass('java.util.Stack')
>>> stack = Stack()
>>> stack.push('hello')
>>> stack.push('world')
>>> print(stack.pop())
world
>>> print(stack.pop())
hello
