Class Facts

java.lang.Object
  org.kuali.rice.krms.api.engine.Facts

All Implemented Interfaces:

Serializable, ModelObjectBasic, ModelObjectComplete

public final class Facts
extends Object
implements ModelObjectComplete, Serializable

Parameter object for the Engine used to pass in mappings from Term to value (aka facts). In rule parlance, a fact is a concrete value of a term. Intuitively this relationship is one of definition and instance, similar to a parameter definition (e.g. int count) for a function (or method) in a programming language and a parameter value (e.g. 5).

Facts is immutable, and has a private constructor. Use the inner Facts.Builder class to construct.
