## Uses of Package
com.hp.hpl.jena.reasoner.rulesys

Packages that use com.hp.hpl.jena.reasoner.rulesys
com.hp.hpl.jena.reasoner | The Jena2 reasoner subsystem is designed to allow a range of inference engines to be plugged into Jena.
com.hp.hpl.jena.reasoner.rulesys | Provides a selection of simple rule engines for Jena inference models.
com.hp.hpl.jena.reasoner.rulesys.builtins | Implementations of the Builtin class which provides primitive operations to the rule engines.

Classes in com.hp.hpl.jena.reasoner.rulesys used by com.hp.hpl.jena.reasoner
ClauseEntry Common interface for all objects that can go into rules.

Classes in com.hp.hpl.jena.reasoner.rulesys used by com.hp.hpl.jena.reasoner.rulesys
BackwardRuleInfGraphI This interface collects together those operations that the backchaining engine needs to invoke in the parent InfGraph.
BasicForwardRuleInfGraph An inference graph interface that runs a set of forward chaining rules to conclusion on each added triple and stores the entire result set.
BindingEnvironment Interface through which the current bound values of variables can be found.
Builtin Rules employ builtins to do all tests and actions other than simple triple matches and triple creation.
BuiltinRegistry A registry for mapping functor names on java objects (instances of subclasses of Builtin) which implement their behvaiour.
ClauseEntry Common interface for all objects that can go into rules.
FBRuleInfGraph An inference graph that uses a mixture of forward and backward chaining rules.
FBRuleReasoner Rule-based reasoner interface.
ForwardRuleInfGraphI This interface collects together the operations on the InfGraph which are needed to support the forward rule engine.
Functor A functor comprises a functor name and a list of arguments.
GenericRuleReasoner A reasoner interface that is able to invoke any of the useful rule engine combinations.
GenericRuleReasoner.RuleMode Class used as an enum for describing rule modes.
GenericRuleReasonerFactory Factory object for creating general rule reasoner instances.
Node_RuleVariable A variation on the normal Node_Variable which support for value bindings.
Rule Representation of a generic inference rule.
Rule.Parser Inner class which provides minimalist parsing support based on tokenisation with depth 1 lookahead.
Rule.ParserException Inner class.
RuleContext Interface used to convey context information from a rule engine to the stack of procedural builtins.
RulePreprocessHook Implementors of this interface can be used as proprocessing passes during intialization of (hybrid) rule systems.
RuleReasoner RuleReasoner - an interface to capture the idea of a Reasoner that relies on Rules; motivated primarily by the testing for ModelSpecs which specify Rules for Reasoners.
SilentAddI Interface supported by each of the rule system interpreters that allow triples to added directly to the deductions cache, by-passing any processing machinery.
