  • Class
    Description
    AndOrSimplifier
    Simplifies a predicate by: - Combining child-AND/OR nodes with direct parents of the same type - Pushing negations down to leaf nodes by using De Morgan's law.
    BooleanSimplifier
    Simplifies a predicate by collapsing TRUE/FALSE-children into their parents.
    ComplexNodeTransformer
    Partitions all the feature ranges according to the arity and bounds set in the PredicateOptions, and updates the ranges with a set of partitions and edge partitions.
    NotNodeReorderer
    Reorders not nodes to improve the efficiency of the z-star posting list compression.
    OrSimplifier
    Simplifies Disjunction nodes where all children are of type FeatureSet.
    PredicateOptions
    This class contains the configured options for predicate indexes.
    PredicateProcessor
    A predicate processor takes a predicate, processes it and returns the result.
