JCC is a C++ code generator for producing the glue code necessary to call into Java classes from CPython via Java's Native Invocation Interface (JNI).

JCC generates C++ wrapper classes that hide all the gory details of JNI access as well Java memory and object reference management.

JCC generates CPython types that make these C++ classes accessible from a Python interpreter. JCC attempts to make these Python types pythonic by detecting iterators and property accessors. Iterators and mappings may also be declared to JCC.
