## What is Easy Rules?
|
|
|
|
Easy Rules is a Java rules engine inspired by an article called *"[Should I use a Rules Engine?](http://martinfowler.com/bliki/RulesEngine.html)"* by [Martin Fowler](http://martinfowler.com/) in which he says:
|
|
|
|
> You can build a simple rules engine yourself. All you need is to create a bunch of objects with conditions and actions, store them in a collection, and run through them to evaluate the conditions and execute the actions.
|
|
|
|
This is exactly what Easy Rules does, it provides the `Rule` abstraction to create rules with conditions and actions, and the `RulesEngine` API that runs through a set of rules to evaluate conditions and execute actions.
|
|
|
|
## Core features
|
|
|
|
* Lightweight library and easy to learn API
|
|
|
|
* POJO based development with annotation programming model
|
|
|
|
* Useful abstractions to define business rules and apply them easily with Java
|
|
|
|
* The ability to create composite rules from primitive ones
|
|
|
|
* Dynamic rule configuration at runtime using JMX
