METHOD, SYSTEM, AND ARTICLE OF MANUFACTURE FOR LIMITING ACCESS TO PROGRAM FILES IN A SHARED LIBRARY FILE

摘要

The present invention limits access to parts of a shared software library (124) by using a class loader (122) that generates a selective interface (210) between an external process (126) and a program file, such as a class definition (200), in the shared library (124). This prevents external processes (126) from loading parts of the shared library (124) that were meant to remain private or internal to the library. The present invention loads a program file, such as a class definition (200), from the shared library (124) and generate an interface, such as an object (210), to the loaded program file (200). A determination of whether the program file can be exported is performed based on a status indicator associated with the interface. The interface limits access to the program file if it is determined that the program can not be exported.
