Class Summary

Class	Description
AbstractDynamicPredicate	INTERNAL: Common code-sharing superclass for dynamic predicates.
AbstractInstanceOfPredicate	INTERNAL: Common superclass for the two instance-of predicates.
AbstractQueryProcessor	INTERNAL: A collection of utility methods used by classes which need to evaluate queries.
AssociationPredicate	INTERNAL: Implements the 'association' predicate.
AssociationRolePredicate	INTERNAL: Implements the 'association-role' predicate.
BaseLocatorPredicate	INTERNAL: Implements the 'base-locator' predicate.
CoalescePredicate	INTERNAL: Implements the 'coalesce' predicate.
DatatypePredicate	INTERNAL: Implements the 'datatype' predicate.
DirectInstanceOfPredicate	INTERNAL: Implements the 'direct-instance-of' predicate using the indexes.
DynamicAssociationPredicate	INTERNAL: Implements association type predicates.
DynamicFailurePredicate	INTERNAL: Special predicate used when a topic is used as a predicate but the topic is neither an association type nor an occurrence type.
DynamicOccurrencePredicate	INTERNAL: Implements occurrence predicates.
EqualsPredicate	INTERNAL: Implements the '=' predicate.
GreaterThanEqualsPredicate	INTERNAL: Implements the '>=' predicate.
GreaterThanPredicate	INTERNAL: Implements the '>' predicate.
InPredicate	INTERNAL: Implements the 'in(var, e1, ..., eN)' predicate.
InstanceOfPredicate	INTERNAL: Implements the 'instance-of' predicate using the indexes.
ItemIdentifierPredicate	INTERNAL: Implements the 'item-identifier(thing, locator)' predicate.
JavaModule	EXPERIMENTAL: A query module that is able to instantiate predicates when given a java class name.
JavaSearcherPredicate	EXPERIMENTAL: Java searcher predicate.
LessThanEqualsPredicate	INTERNAL: Implements the '<=' predicate.
LessThanPredicate	INTERNAL: Implements the '<' predicate.
NamePredicate	INTERNAL: The implementation of the 'name(topic, name-string)' predicate.

ParsedQuery	INTERNAL: Class used to represent parsed queries.
PredicateFactory	INTERNAL: The basic predicate factory implementation.
PredicateUtils	INTERNAL: Shared utilities for the predicate implementations.
QueryContext	INTERNAL: Object used to hold the global query execution context; that is, the context beginning with the start of the execution of a query and ending with the completion of its execution.
QueryMatches	INTERNAL: Object used to hold query results during computation.
QueryProcessor	INTERNAL: This query processor implementation can be used to query any topic map implementation; it makes no assumptions about the stored form of the topic map.
QueryResult	INTERNAL: The query result representation used by the basic implementation.
QueryResultWrappers	INTERNAL: Collection of QueryResult wrapper classes.
QueryTracer	INTERNAL: Used for testing and timing of queries.
QueryTracer.TracePrinter

ScopePredicate	INTERNAL: Implements the 'scope(scoped, theme)' predicate.
StringModule
SubjectIdentifierPredicate	INTERNAL: Implements the 'subject-identifier(topic, locator)' predicate.
