Title:
共用ライブラリファイル内のプログラムファイルへのアクセスを制限するための方法、システムおよび記憶媒体
Document Type and Number:
Japanese Patent JP4841787
Kind Code:
B2
Abstract:
Methods, systems, and articles of manufacture consistent with the present invention limit access to parts of a shared software library by using a class loader that generates a selective interface between an external process and a program file (such as a class definition) in the shared library. This prevents external processes from loading parts of the shared library that were meant to remain private or internal to the library. Methods, systems, and articles of manufacture consistent with the present invention load a program file, such as a class definition, from the shared library and generate an interface (such as an object) to the loaded program file. A determination of whether the program file can be exported is performed based upon a status indicator associated with the interface. The interface limits access to the program file if it is determined that the program file cannot be exported.
