Package org.kuali.rice.krms.api.engine

Class Facts

java.lang.Object
org.kuali.rice.krms.api.engine.Facts
All Implemented Interfaces:
Serializable, org.kuali.rice.core.api.mo.ModelObjectBasic, org.kuali.rice.core.api.mo.ModelObjectComplete
public final class Facts extends Object implements org.kuali.rice.core.api.mo.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.
