Method of Reproducing Interface Cord Between Object Oriented CHILL Compiler and Distributed Object Executor that is Middleware

摘要

PURPOSE: A method for creating a matching code with an objected-oriented CHILL(ITU-T High Level Language) compiler and a middleware distributed object executing device is provided to prepare and execute a distributed object program by creating/compiling a matching code, thereby compiling an objected-oriented CHILL distributed program at the same time and creating an execution file for supporting a distributed object function. CONSTITUTION: A sentence structure analyzing unit and a word meaning analyzing unit of an objected-oriented CHILL compiler perform a sentence structure analysis and a word meaning analysis, and create a symbol table and an AST(Abstract Syntax Tree)(301). If an entry is not a task mode definition with respect to each entry of the symbol table(302), it is judged whether the entry is a task section(304). If the entry is a task section, a distributed object executing device(for example, EDOM(ETRI(Electronics and Telecommunication Research Institute) Distributed Object Manager)) thread is created, and the created distributed object executing device thread creates a distributed object code(305). If an execute statement is a distributed object method call(307), a marshaling with respect to a factor is performed and a code for calling a message transmitting sentence structure is created by making a string obtained by the marshaling as a message, and a conversion to the C++ language is achieved(308).
