where is the implement of function `NewString` in `jbinding-cpp/UnicodeHelper.h'`

[BTYHunter]

Sorry I can not find the implement of NewString function in 'jbinding-cpp/UnicodeHelper.h' (I have searched the whole project code).
Below is the code.

 jstring toNewString(JNIEnv * env) {
    return env->NewString((const jchar *)*this, _unicodeLength);
 }

Thanks for you reply.
@borisbrodski Would you please help?

Sure. NewString ist jni-function:

jstring NewString(const jchar *unicode, jsize len) {
    return functions->NewString(this,unicode,len);
}
