public ListFilteredDimensionSpec(DimensionSpec delegate,
 Set<String> values,
 Boolean isWhitelist)

Method Details

getValues

public Set<String> getValues()

isWhitelist

public boolean isWhitelist()

decorate

public DimensionSelector decorate(DimensionSelector selector)

Description copied from interface: DimensionSpec

Decorate a DimensionSelector, allowing custom transformation of underlying behavior (e.g. performing extraction functions in the case of ExtractionDimensionSpec, regex filtering in the case of RegexFilteredDimensionSpec, and so on).

buildAllowListIdMapping

public static IdMapping buildAllowListIdMapping(Set<String> values,
 int cardinality,
 @Nullable
 IdLookup idLookup,
 ListFilteredDimensionSpec.IndexedGetter<String> fn)

buildDenyListIdMapping

public static IdMapping buildDenyListIdMapping(Set<String> values,
 int cardinality,
 ListFilteredDimensionSpec.IndexedGetter<String> fn)

filterAllowList

public static DimensionSelector filterAllowList(Set<String> values,
 DimensionSelector selector,
 boolean forcePredicateFilter)

filterDenyList

public static DimensionSelector filterDenyList(Set<String> values,
 DimensionSelector selector,
 boolean forcePredicateFilter)

getCacheKey

public byte[] getCacheKey()

Description copied from interface: Cacheable

Get a byte array used as a cache key.

Returns:

bytes to be used as cache key - or null if this object should not be cached.

withDimension

public DimensionSpec withDimension(String newDimension)

Description copied from interface: DimensionSpec

Returns a copy of this DimensionSpec with the underlying dimension (the value of DimensionSpec.getDimension()) replaced by "newDimension".

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
