jnr-fuse

jnr-fuse is a FUSE implementation in java using Java Native Runtime (JNR).

Project Goals

The main goal of the project is to provide an easy way to create a high-performance filesystem in userspace.

About technologies

FUSE (Filesystem in Userspace) is an OS mechanism for unix-like OS that lets non-privileged users create their own file systems without editing kernel code.

Java Native Runtime (JNR) is high-performance Java API for binding native libraries and native memory.

How to use

For implementing your own filesystem you just need to extend FuseStubFS class and implement methods you need.

See some examples.
