Scapix JNI

🇺🇦 If you like this project, please consider donating to one of the funds helping victims of russian aggression against Ukraine: ukraine.ua

Modern C++20 wrapper for JNI (Java Native Interface):

  • type-safe APIs
  • automatic resource management
  • ZERO runtime overhead compared to manually written JNI code
  • automatic C++/Java type conversion for many standard types (std::string, std::vector, etc.)
  • automatic C++/Java exception tunneling
  • comes with pre-generated C++ headers for all JDK and Android Java APIs
  • automatically generate C++ headers for any Java code, including your own
// Generated headers for all JDK/Android classes:

#include <scapix/java_api/java/lang/System.h>
#include <scapix/java_api/java/util/Locale.h>
#include <scapix/java_api/java/text/DateFormatSymbols.h>

using namespace scapix::java_api;

void test()
{
    // Automatic conversion between common C++ and Java types (std::string, std::vector, std::map, etc):

    std::string version = java::lang::System::getProperty("java.version");
    std::vector<std::string> languages = java::util::Locale::getISOLanguages();
    std::vector<std::vector<std::string>> zone_strings = java::text::DateFormatSymbols::getInstance()->getZoneStrings();
    std::map<std::string, std::string> properties = java::lang::System::getProperties();
}
