Master: Develop: Travis CI

Cascade is easily debugged, non-blocking concurrent functonal-reactive programming for Android. The goals are safety, clear async algorithms, easy debugging, and raw speed through clean flow between constraint-based thread pools.

NET.then("http://service.com/model") .then(WORKER, s -> parse(s)) .then(UI, model -> display(model));

Key advantages:

1. high performance for great UX

• everything is concurrent by default; serial execution is available
• keep all cores lit while minimizing context swtiching and work in progress
• CPU-bound tasks are up to Nx faster on a N core device
• file system, network and general CPU tasks never accidentally "leak" onto the UI thread

1. strict and explicit

• threadgroup for execution is defined by a method, not how it is called
• code binding context is always explicitly defined and cleaned
• minimal boilerplate

1. easy to read

• small, consistent library to minimize learning time
• minimal glue objects; lambda-friendly interfaces help see the complete flow of code in one place

1. easy to write

• just play; most tasks are easy when everything is thread safe
• clear, explicit contracts; extensive use of generics and runtime assertions
• easily configure the runtime builder and substitute alternate implementations and default behaviors

1. easy to debug

• track asynchronous effects back to their origin with clickable links in the log
• error messages guide you back to where the error was induced by showing object creation and async invocation points

You can freely use the flow-of-control style which makes the most sense

1. functional chains

• composable, immutable object chains for traditional procedural code
• ideal for use with existing APIs such as Android
• objects become immutable value holders once executed

1. reactive chains

• data driven where this makes more sense
• subscribe concurrent actions to atomic variables
• objects representing intermediate functions in a chain are re-used during concurrent execution

How to use: Clone and play. This is a pre-release work in progress. We refactor when a better way of doing things becomes clear. At the moment it is subject to change.
