 This library is a lightweight, easy-to-use implementation of the http://martinfowler.com/bliki/CircuitBreaker.html[CircuitBreaker pattern] optimized for Java 8 and functional programming in a multithreaded environment.
-The library provides several higher-order functions to decorate any `Supplier / Runnable / Function` or `CheckedSupplier / CheckedRunnable / CheckedFunction` with a Circuit Breaker. In the following I call the higher-order functions `decorators`. The decorators return an enhanced version of your function. Furthermore, the library provides decorators to measure runtime metrics of your functions by using https://dropwizard.github.io/metrics/[Dropwizard Metrics]. You can stack more than one decorator on any given function. That means, you can combine a Metrics decorator with a CircuitBreaker decorator. Any decorated function can be invoked synchronously or asynchronously.

In the following I call the higher-order functions `decorators`. The decorators return an enhanced version of your function. Furthermore, the library provides decorators to measure runtime metrics of your functions by using https://dropwizard.github.io/metrics/[Dropwizard Metrics] and decorators to retry failed functions. You can stack more than one decorator on any given function. That means, you can combine a Metrics decorator with a CircuitBreaker decorator. Any decorated function can be invoked synchronously or asynchronously.
 The project should be combined with a functional library for Java 8 like https://github.com/javaslang/javaslang[javaslang]. The project requires at least JDK 8.
 
 The CircuitBreaker is implemented via a finite state machine with three states: `CLOSED`, `OPEN` and `HALF_OPEN`. The CircuitBreaker does not know anything about the backend's state by itself, but uses the information provided by the decorators via `CircuitBreaker::recordSuccess()` and `CircuitBreaker::recordFailure(throwable)`. The decorators are pure functions. The result of a decorator depends solely on the input parameters. See example:
