[Rxtx] Which Java folder in source?

[Adrian Crum]

Just to make sure I'm understanding you correctly, anyone porting RxTx 
to a new platform would have to do the following:

1. Write their own Java implementation of an abstract Dispatcher class.
2. Write a native (JNI or JNA) interface for the abstract class 
implementation.
3. Write all of the native (or non-native) code to implement the native 
interface.

Is that correct? If yes, how is that easier than the simple 
implementation the current rewrite design uses?

On a side note: there is no requirement to write native code using C++. 
If C++ is a real obstacle to adoption, then regular C could be used 
instead. In that case, there would be a Dispatcher.c file that contains 
function protoypes that need to be implemented. Dispatcher.c would still 
maintain the same role as Dispatcher.cpp - which is to shield native 
code developers from the details of JNI. Just build out the missing 
functions using C data types and you're ready to go.
