Method for script language calling multiple output parameter interface by component software system

Abstract

The invention relates to a method of multiple output parameter interface for realizing script language calling in a component based software system, which comprises that: a system generates call statement of a script language to an interface method of the component object, the script engine reads the call information, the script engine passes through the call information to the interface method according to the meta-information of the interface method, the script engine judges whether the interface method contains output parameter, if yes, the operating processing that the output parameter variable dynamic generating being sent to the interface method can be carried through, the script engine calls the interface method, the script engine transforms the output parameter variable into output information matching the script data type and then returns to the system. By adopting the method of multiple output parameter interfaces for realizing script language calling in the component based software system, the adaption problem of the output parameter returned value of the script language calling component during the interface method is effectively solved, the invention has simple realization process, relatively high code execution efficiency, convenient and rapid operation, as well as stable and reliable working performance and relatively wide application scope.

Description

technical field [0001] The present invention relates to the field of computer software, in particular to the technical field of componentized software systems, in particular to a method for realizing script language invoking multiple output parameter interfaces in componentized software systems. Background technique [0002] With the continuous development of computer software technology, various advanced embedded operating systems have emerged, and the CAR (Component Assembly Runtime) technology formed on these embedded operating systems provides a convenient solution for component-based software development. This technology is a binary component technology based on C / C++, which is mainly used in embedded devices. [0003] A CAR component library is generally a dynamic link library (Dynamic Link Library) file, which contains several CAR objects and meta-information related to CAR components. A CAR object provides services by exposing several interfaces. To generate a CAR c...
