SWIG：如何将复数向量从 C++ 传递到 Java

Question

%include <std_complex.i>

manager.i:21: Error: Unable to find 'std_complex.i'

Answer 1

Swig documentation (*) says:

some language modules support a subset of the above and some support additional STL classes. Please look for the library files in the appropriate language library directory.

therefore it appears that std_complex.i is not implemented for Java as the target language. The reason may be that Java does not have a data type for complex numbers.

In order to interface existing C++ code that uses complex numbers to Java with swig, you would have to write your own type maps or write wrapper functions in C++ that accept and return separated real and imaginary parts.
