All Implemented Interfaces:

java.io.Serializable
```
public final class Fact
extends java.lang.Object
implements java.io.Serializable
```
Represents a contextual artifact, which can be any serializable object, useful for making a Decision. Facts are key-value pairs, where the key is a String (message key) and the value is an arbitrary object. Generally, the supplied object's toString() method should return a human-readable String. Facts are immutable objects.
