Abstract
This paper addresses the issues faced when constructing an operating system and its kernel with object-oriented technology. We first propose object/metaobject separation, a means of constructing an object-oriented operating system and its kernel. This method divides the implementing system facilities and applications into two types: objects and metaobjects. This paper presents the concept of object/metaobject separation and discusses why object/metaobject separation is required in terms of limitations in the micro-kernel and object-oriented technologies. We also discuss an example of using object/metaobject separation as implemented in Apertos. This paper then proposes mechanisms which efficiently implement object/metaobject separation. These are characterized by meta-level context management, and are implemented in the Apertos operating system. Meta-level context management is designed to reduce the overhead of control transfer between an object and its metaspace. Here, metaobjects re...
