You should consider Boost.Python if you are not planning to generate bindings for other languages as well with swig. If you have a lot of functions and classes to bind, Py++ is a great tool that automatically generates the needed code to make the bindings. Pybindgen may also be an option, but it’s a new … Read more
The easiest way to do this is to wrap your arrays inside a struct, which can then provide extra methods to meet the “subscriptable” requirements. I’ve put together a small example. It assumes you’re using C++, but the equivalent C version is fairly trivial to construct from this, it just requires a bit of repetition. … Read more
The crux of this is that to wrap either of these functions you’ll want to use a multi-argument typemap. The preamble is pretty standard for SWIG. I used my personal favourite prgama to automatically load the shared library without the user of the interface needing to know: %module test %{ #include “test.hh” %} %pragma(java) jniclasscode=%{ … Read more
You can achieve what you’re looking for with SWIG+Java using “Directors”, however it’s not quite as straightforward mapping from the C++ abstract classes onto Java as you might hope. My answer therefore is split into three parts – firstly the simple example of implementing a C++ pure virtual function in Java, secondly an explanation of … Read more
I am currently working on an Android application which streams radio. I use native decoder library which is called aacdecoder. Everything was fine till app gets crash error on some Android devices. It was really annoying. Because app was perfectly plays radio streams almost all devices but Samsung S6 and S6 Edge. Crash report says … Read more
You can do this if you have a chance to pass some data around with the callback, but you’ll need to write some JNI glue. I put together a complete example of how you might map C style callbacks onto a Java interface. The first thing you need to do is decide on an interface … Read more
There’s two parts to this answer. First you need to expose your interface in Python in a way which allows Python implementations to override parts of it at will. Then you need to show your C++ program (in main how to call Python. Exposing the existing interface to Python: The first part is pretty easy … Read more
