Djinni - A tool for generating cross-language type declarations and interface bindings.

Djinni is a tool for generating cross-language type declarations and interface bindings. It's designed to connect C++ with either Java or Objective-C. Python support is available in an experimental version on the python branch.We at Dropbox use Djinni to interface cross-platform C++ library code with platform-specific Java and Objective-C on Android and iOS.

• Generates parallel C++, Java and Objective-C type definitions from a single interface description file.
• Supports the intersection of the three core languages' primitive types, and user-defined enums, records, and interfaces.
• Generates interface code allowing bidirectional calls between C++ and Java (with JNI) or Objective-C (with Objective-C++).
• Can autogenerate comparator functions (equality, ordering) on data types.
