In one implementation, a shared function is specified by means of a naming convention that is appropriate for the bytecode interpreted program, such as a package of classes. When a native method is to be resolved during loading of a class, the name of the package is examined to see if the method resides in a shared library. If so, it is loaded using techniques that are specific to the compiled code in which the library exists. In another embodiment, a designated base class, or interface, is used to identify the method by which the shared library is to be loaded. In a third type of implementation, a given method requests a class to specify which libraries it needs to be linked to, as it is being loaded, after which the libraries are loaded and the class methods are linked to them.Other References
