That's the approach we've taken with Renjin and GNU R's C API.
You can basically tell the compiler to map a C struct to a given java
class, for example, mapping CRuby's VALUE to org.jruby.RubyBasicObject and
import
GimpleCompiler compiler = new GimpleCompiler();
compiler.addRecordClass("__VALUE", RubyBasicObject.class);
compiler.addMethod("TYPE", CRuby.class, "TYPE");
You can then define:
class CRuby {
public static int TYPE(RubyBasicObject obj) {
if(obj instance of RubyBoolean) return 1;
if(obj instance of RubyHash) return 2;
// etc...
}
}
We monkey with the GNU R header files to make replace macros with function
declarations so they can mapped to JVM methods.
