Class NativeLoader

java.lang.Object

com.swoval.runtime.NativeLoader

public class NativeLoader
extends java.lang.Object

Manages the loading of the swoval-files0 library. This library provides the native implementation of FileTreeView. On OSX, it also provides a native interface to the apple file system api. The loader will first try to load the library using System.loadLibrary, which will succeed if the library is present in the (DY)LD_LIBRARY_PATH. Otherwise the loader extracts the packaged library (.so, .dll or .dylib) to a temporary directory and loads it from there. On jvm shutdown, it marks the extracted library for deletion. It will generally be deleted the next time a different jvm loads the library.

This class is not intended to be used outside of com.swoval.files, but it doesn't belong in that package, so it has to be public here.

                                java.lang.UnsatisfiedLinkError

Loads the swoval-files0 shared library. It will first try to load the library from the system library path and fallback to extracting a platform-specific jar to a temporary directory.

Throws:

java.io.IOException - if the packaged native binary cannot be written to a temp directory.

java.lang.UnsatisfiedLinkError - if no compatible binary for the platform is present.
