Overview of Provided Classes

arakhneVmutils library contains the following tools:

• org.arakhne.vmutil.ReflectionUtil: provides a set of utility functions which are extending the Class's functions with reflection and autoboxing support (getPackageClasses, isInstance, isAssignableFrom...).
• org.arakhne.vmutil.Caller: is a facility class to retreive the classes that are calling a function (stack exploration).
• org.arakhne.vmutil.ClassLoaderFinder: provides a singleton repository of ClassLoader instances.
• org.arakhne.vmutil.DynamicURLClassLoader: is the implementation of a ClassLoader which is able to update the class paths with URLs.
• org.arakhne.vmutil.FileSystem: provides file system utilities (dirname, split...).
• org.arakhne.vmutil.LibraryLoader: provides a convenient way to load native dynamic libraries. It extends the default JVM loading functions by the ability to load a library from remote sources (URL-based location) or from a archive (Jar...).
• org.arakhne.vmutil.OperatingSystem: provides an enumeration of operating systems and permits to retreive the current operating system.
• org.arakhne.vmutil.VMCommandLine: provides a set of functions to parse and store the command line arguments. It also permits to relaunch a virtual machine with the stored command line.
• org.arakhne.vmutil.locale.Locale: provides utility functions to retreive localized strings from property files.
