Constructor Detail

ListFilteredDimensionSpec

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

Method Detail

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).
