Abstract

The invention discloses a method for invoking C++ functional module in a Java program. The method includes: allowing a Java program to receive a parameter required by the C++ functional module, allowing the Java program to operate an intermediate program and transmitting the parameter to the intermediate program; allowing the intermediate program to invoke the C++ functional module so as to acquire an execution result corresponding to the parameter, and returning the execution result to the Java program. According to the invention, the intermediate program is executed in a Java code, the C++ functional module is indirectly invoked in a value passing manner, the problem of the low efficiency of invoking of the C++ functional module in the Java program can be solved, and the development efficiency of hybrid programming and the operation efficiency are improved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method for calling a C++ function module in a Java program. Background technique [0002] The Java language is an object-oriented programming language. This programming language has the characteristics of simplicity, object-oriented support, distribution, robustness, security, platform independence and portability. As a representative of static object-oriented programming language, Java language has the characteristics of powerful function and easy-to-use. Compared with the Java language, the C++ language has its own characteristics. C++ language is an object-oriented programming language developed on the basis of C language. This language has functions and features such as supporting classes, supporting encapsulation, inheritance, and polymorphism. Because C++ language has the same characteristics of high operating efficiency as C language , so C++ language is often use...
