Problems solved by technology

[0003] However, the existing distributed virtual test architectures, such as HLA (high level architecture), DIS (Distributed Interactive Simulation), etc., only stipulate test simulation rules, object model templates and test simulation member interface specifications, and lack the object model framework Research on Automatic Code Generation Technology
Therefore, the object model of the distributed virtual test requires application developers to manually write codes, the application efficiency and reliability are not high, and because the model lacks a unified description, it brings difficulties to the sharing and reuse of test resources

Abstract

A frame code automatic generating method of a virtual test distributed type object model is used for finishing conversion of the object model from descriptive language text to frame codes of standard C++ syntax format. The method includes defining a descriptive language of the virtual test distributed type object model, conducting lexical analysis and grammatical analysis on text files of the virtual test distributed type object model and described by the language, building a mapping relation between the descriptive language and interface definition language (IFL), calling an IDL complier to generate the corresponding frame codes of the virtual test distributed type object model, building a distributed type object model template and utilizing label substitution to generate codes of the virtual test distributed type object model. The virtual test distributed type object descriptive language achieves standardized description of a virtual test distributed type object, and is favorable for reusing and combination of test resources. The frame code automatic generating method of the virtual test distributed type object model reduces working amount of developers and improves reliability and efficiency of application development.

Description

technical field [0001] The invention relates to a method for automatically generating frame codes of a virtual test distributed object model, belonging to the technical field of virtual tests. Background technique [0002] At present, due to the characteristics of multi-model, multi-node, wide distribution, and heterogeneity in virtual experiments, a distributed architecture is often used among each experimental node. How to construct distributed object models efficiently and reliably, and realize the reusability and composability of the models has become a major research direction in the field of virtual experiments. [0003] However, the existing distributed virtual test architectures, such as HLA (high level architecture), DIS (Distributed Interactive Simulation), etc., only stipulate test simulation rules, object model templates and test simulation member interface specifications, and lack the object model framework Research on automatic code generation technology. The...
