Package no.sesat.search.query.token

Interface Summary

AbstractEvaluatorFactory.Context	The context the RegExpEvaluatorFactory must work against.
TokenEvaluationEngine	TokenEvaluationEngine contains state as to what is the current term being tokenised, and the term's sets of known and possible predicates.
TokenEvaluationEngine.Context
TokenEvaluationEngine.State	Holder for evaluation state during the engine's evaluation.
TokenEvaluationEngineContext
TokenEvaluator	TokenEvaluator works behind a TokenPredicate doing the actual work to prove the predicate true or false.
TokenPredicate	A Categorisation of knowledge that attaches itself as meta-data to words and groups of words (clauses) within a query.

Class Summary

AbstractEvaluatorFactory	EvaluatorFactory responsible to finding appropriate factory subclass to use given the context.
AbstractTokenPredicate	Base class helping with equals, hashcode, and toString overrides which all TokenPredicate implementations share.
DeadTokenEvaluationEngineImpl	A dead evaluation engine.
EvaluationState	Default implementation of TokenEvaluationEngine.State.
EvaluatorType	Deprecated. An automatic approach is required, similar to how AnalysisRuleFactory warms up EvaluatorFactories.
ExactTokenPredicateImpl	An token predicate peer that only evaluates to true against its original token predicate on exact query matches.
FastQueryMatchingEvaluatorFactory	Responsible for loading and serving the VeryFast (Fast Query Matching) Token Evaluator.
JepEvaluatorFactory	Responsible for loading and serving the JEP Expression Token Evaluators.
JepTokenEvaluator	Evaluates whether a term or query forms a mathimatical expression.
RegExpEvaluatorFactory	Responsible for loading and serving all the Regular Expression Token Evaluators.
RegExpTokenEvaluator	An implementation of TokenEvaluator which uses a set of Pattern to decide if a token occurs in a query.
SolrEvaluatorFactory
SolrTokenEvaluator
TokenEvaluationEngineImpl	TokenEvaluateFactory provides knowledge about which implementation of TokenEvaluator that can handle a particular token.
TokenPredicateImpl	The default implementation used.
TokenPredicateUtility	Utility class providing all useful static methods around TokenPredicates.
VeryFastTokenEvaluator	VeryFastTokenEvaluator is part of no.sesat.search.query.

Enum Summary

Categories

A formalised breakdown of metadata categories that search terms can match.

Exception Summary

EvaluationException	Something went wrong evaluating the token.
EvaluationRuntimeException	Runtime exception thrown when evaluation fails.
