 net.xoetrope.os.LibraryLoader
| LibraryLoader | | public class LibraryLoader (Code) | | Loads a native library file. The class can load the library by attempting to
have the Sytem class load the library from the library path. If this fails the
class can attempt to load the file by extracting it from the classpath,
including the Jar files on the classpath and then loading it with the full
file path. A temporary directory is used to temporarily extract the file.
If the file is loaded successfully the library name is placed in a hashtable
so that subsequent calls to load the library to not actually attempt to
load the library.
