## SWIG wrapped and manually wrapped functions in Java

Click here for the relevant section in the SWIG and Java documentation.

This example compares wrapping a c global function using the manual way and the SWIG way.

- example.i. Interface file comparing code wrapped by SWIG and wrapped manually.
- runme.java. Sample Java program showing calls to both manually wrapped and SWIG wrapped c functions.

## Notes

- SWIG writes all the awkward JNI code for you. You just have to tell SWIG which functions to wrap.
- If memory is allocated in c it needs to be free'd. A function, such as free(), can be provided with access from Java to free the memory.
