Foreign Function & Memory API
This repository contains changes which aim at improving the interoperability between the Java programming language and native libraries, which is one of the main goals of Project Panama. This is done by introducing a new Java API, the Foreign Function & Memory API, which can be used to:
- interact with different kinds of memory resources, including so-called off-heap or native memory, as shown here;
- find native functions in a .dll/.so/.dylib and invoke them using method handles, as shown here.
This API has been delivered, as incubating/preview APIs, in official JDK releases, see JEP 412, JEP 419 and JEP 424 for more details.
The Foreign Function & Memory API is best used in combination with a tool called jextract, which can be used to generate Java bindings to access functions and/or structs in a native library described by a given header file. The tool is available in a standalone repository which contains several examples which should help you getting started.
