Method Detail

makeValueMatcherGeneric

public static ValueMatcher makeValueMatcherGeneric(DimensionSelector selector,
                                                   String value)

Generic implementation of DimensionSelector.makeValueMatcher(String), uses DimensionSelector.getRow() of the given DimensionSelector. "Lazy" DimensionSelectors could delegate makeValueMatcher() to this method, but encouraged to implement makeValueMatcher() themselves, bypassing the IndexedInts abstraction.

makeValueMatcherGeneric

public static ValueMatcher makeValueMatcherGeneric(DimensionSelector selector,
                                                   com.google.common.base.Predicate<String> predicate)

Generic implementation of DimensionSelector.makeValueMatcher(Predicate), uses DimensionSelector.getRow() of the given DimensionSelector. "Lazy" DimensionSelectors could delegate makeValueMatcher() to this method, but encouraged to implement makeValueMatcher() themselves, bypassing the IndexedInts abstraction.

makePredicateMatchingSet

public static BitSet makePredicateMatchingSet(DimensionSelector selector,
                                              com.google.common.base.Predicate<String> predicate)

public static DimensionSelector constantSelector(@Nullable
                                                 String value)
