Package biz.hammurapi.rules

Interface Summary

Action	Instances of this class represent actions performed by the engine in response to adding an object to working memory.
ActionTracer	Rules container which implements removal by tracing conclusions to causes shall implement this interface.
CollectionManager	Implementations manage collections for rules.
Constants	Constants.
Fact	This interface allows to indicate that some conclusion is internal for the rule engine, i.e.
FactSource	Source of facts of particular type(s).
Handled	Classes which "know" about their handles shall implement this interface.
HandleManager	Handle manager - creates and maintains handle -> object mappings.
KnowledgeBase	This interface is a facade for object dispatchers.
KnowledgeBase.KnowledgeBaseCommand	Interface for dispatching commands to knowledge bases.
KnowledgeCompactor	Implementations of this interface preprocess object collections before returning them from RuleSession.getObjects().
Negatable	Classes which have complex negating semantics should implement this interface.
Negator	Facts which negate other facts shall implement this interface
ObjectStorage	Implementations of this class can be used by Handle and Collection managers implementations to persist engine state
Rule.AcceptInfo	Instances of this interface are passed to accept() methods as second parameter.
Rule.ChangeDetector	Interface to detect changes in arguments passed to inference methods.
SmartHandle	Handle which knows how to obtain master reference.
Supercedable	Classes which can supercede each other shall implement this interface.

Class Summary

AbstractRule
Conclusion	Base class for conclusions.
ConclusionNegator	Negates conclusions equal or superceding the conclusion passed to the constructor
Derivation	This class is a tracking element for inference process.
EqualityNegator	Negates objects which are equal to the object passed to the constructor.
FileObjectStorage
IdentityHandleManager	Handle manager implementation which keeps handles in memory.
IdentityNegator	Negates the object passed to the constructor.
KnowledgeMaximizingCompactor
KnowledgeMaximizingHandleManager	Handle manager implementation which keeps handles in memory.
KnowledgeMaximizingSet	This class "maximizes knowledge", which means when more specific (superceding) conclusions are added to the set less specific are removed.
ObjectNegator	Negates object whose handles are equal to handle of the object passed to the constructor.
PojoCollectionManager	Collection manager which holds collections in memory and can use storage to persist state.
QueueingRulesContainer	This rules container uses QueuingDispatcher and negation semantics for remove().
Rule	Base class for rules.
RulesContainerBase	Base class for containers of rules.
SimpleConclusion	Exposes Conclusion's put() and get() methods.
