Interface FactType

All Superinterfaces:

Externalizable, Serializable

public interface FactType
extends Externalizable

FactType declarations are fact definitions (like classes) that are managed alongside the rules. You then communicate with the rulebase/knowledge base by using instances created by this. There are utility set and get methods on this, as well as in the FieldAccessors. The Object that is used is a javabean (which was generated by the rules). You can also use reflection on it as normal.

Method Summary

Modifier and Type	Method	Description
Object	get(Object bean, String field)	get the value of the specified field on the dynamic fact.
Map<String,Object>	getAsMap(Object bean)	Get a map of the fields and their values for the bean.
Class<?>	getFactClass()
FactField	getField(String name)
List<FactField>	getFields()
String	getName()
Object	newInstance()	Create a new fact based on the declared fact type.
void	set(Object bean, String field, Object value)	Set the value of the field on a dynamic fact.
void	setFromMap(Object bean, Map<String,Object> values)	Set the values of the bean from a map.
