Uses of QueryOptimizer.AbstractQueryOptimizer in net.ontopia.topicmaps.query.impl.utils

Subclasses of QueryOptimizer.AbstractQueryOptimizer in net.ontopia.topicmaps.query.impl.utils

static class	QueryOptimizer.AddTypeToRolePlayer INTERNAL:
static class	QueryOptimizer.HierarchyWalker Replaces simple recursive rules with a more efficient custom implementation that just wraps the recursive step.
static class	QueryOptimizer.NextPreviousOptimizer INTERNAL: Optimizes queries that look for the next or the previous value in a sequence from a given start value to not load all values and then do it the hard way, but instead to use a sorted index.
static class	QueryOptimizer.RecursivePruner This optimizer adds RemoveDuplicatesPredicate on both sides of recursive calls within predicate rules.
static class	QueryOptimizer.Reorderer INTERNAL: Optimizes the query by reordering the clauses into the optimal order for evaluation.
static class	QueryOptimizer.RuleInliner INTERNAL: Optimizes the query by inlining all rules which are simple aliases for a single predicate.
static class	QueryOptimizer.StringPrefixOptimizer INTERNAL: Optimizes queries that do lookup of occurrences by string value, then filter the string value by a prefix.
static class	QueryOptimizer.TypeConflictResolver Finds cases of conflicting variables and resolves them by replacing predicates which can never succeed with DynamicFailurePredicate.
