| RuleInstance | | public class RuleInstance (Code) | | Part of the backward chaining rule interpreter. A RuleInstance
links an instance of a rule to the GoalResults object for which it is
generating results. It is a simple data structure which is shared amongst
a set of RuleSets to reduce the store turn over needed for RuleState creation.
Encapuslation warning: this object is used in the tight inner loop of the engine so we access its
field pointers directly rather than through accessor methods.
