| Research Abstract |
This research is aimed at developing a programming environment for an object oriented language, where the user can find out and reuse existing classes.
First, wer have proposed "Acquaintance/Component Variable Model," which is an object model describing features and properties of objects and operations clearly, and we have developed an object oriented language MOMO based on the model and its class library MOMOCLI.
Second, we have developed a tool for retrieving classes from MOMOCLI. This tool reads the "query description." This description is described by the user about the objects and operations he/she wants, based on the Acquaintance/Component Variable Model. The retrieval tool retrieves candidate classes for implementing the required objects and candidate methods for implementing the required operations, from MOMOCLI.
The retrieval is performed by applying production rules stored on a knowledge base. The knowledge base includes rules for consulting a dictionary, rules for checking relations and properties defined on the Acquaintance/Component Variable Model, rules for removing unimplemented candidates, etc. By introducing the dictionary, the tool enables the user to use arbitrary names for objects and operations. The candidates are displayed with graphics. The user can select the most appropriate candidates by browsing the candidates with the tool.
We have also developed a tool for registering new classes to MOMOCLI, and a tool for editing query descriptions and MOMO programs. The three tools construct the programming environment of our goal. The user can describe a query description, retrieve classes and methods fromt he library, and construct the MOMO program in this environment.
