# capnproto-java: Cap'n Proto for Java

[Cap'n Proto](http://capnproto.org) is an extremely efficient protocol for sharing data
|
|
and capabilities, and capnproto-java is a pure Java implementation.

This repository clone adds an implementation of the RPC framework for Java.
|
|
|
|
Promise pipelining is provided via java.util.concurrent.CompletableFuture. Unlike the KJ asynchronous model, which completes promises
|
|
only when they are waited upon, a CompletableFuture can complete immediately. This may break E-ordering, as the C++ implementation
|
|
relies on kj::evalLater() to defer method calls and this implementation may have subtle differences.
|
|
|
|
Most of the C++ RPC test cases have been ported to this implementation, which gives me some comfort that the implementation logic is
|
|
correct, but more extensive testing is required.
|
|
|
|
This implementation does not support generic interfaces. Extending the schema compiler to output code for generic interfaces is an
|
|
exercise I leave to the reader.
