Uses of IndexExtractor in org.apache.commons.collections4.bloomfilter

Subinterfaces of IndexExtractor in org.apache.commons.collections4.bloomfilter

Modifier and Type	Interface	Description
interface	BloomFilter<T extends BloomFilter<T>>	The interface that describes a Bloom filter.
interface	CellExtractor	Some Bloom filter implementations use a count rather than a bit flag.
interface	CountingBloomFilter	The interface that describes a Bloom filter that associates a count with each bit index rather than a bit.

Classes in org.apache.commons.collections4.bloomfilter that implement IndexExtractor

Modifier and Type	Class	Description
final class	ArrayCountingBloomFilter	A counting Bloom filter using an int array to track cells for each enabled bit.
class	LayeredBloomFilter<T extends BloomFilter<T>>	Layered Bloom filters are described in Zhiwang, Cen; Jungang, Xu; Jian, Sun (2010), "A multi-layer Bloom filter for duplicated URL detection", Proc. 3rd International Conference on Advanced Computer Theory and Engineering (ICACTE 2010), vol. 1, pp.
final class	SimpleBloomFilter	A bloom filter using an array of bit maps to track enabled bits.
final class	SparseBloomFilter	A bloom filter using a TreeSet of integers to track enabled bits.
class	WrappedBloomFilter<T extends WrappedBloomFilter<T,W>,W extends BloomFilter<W>>	An abstract class to assist in implementing Bloom filter decorators.

Methods in org.apache.commons.collections4.bloomfilter that return IndexExtractor

Modifier and Type	Method	Description
static IndexExtractor	IndexExtractor.fromBitMapExtractor(BitMapExtractor bitMapExtractor)	Creates an IndexExtractor from a BitMapExtractor.
static IndexExtractor	IndexExtractor.fromIndexArray(int... values)	Creates an IndexExtractor from an array of integers.
IndexExtractor	EnhancedDoubleHasher.indices(Shape shape)
IndexExtractor	Hasher.indices(Shape shape)	Creates an IndexExtractor for this hasher based on the Shape.
default IndexExtractor	BloomFilter.uniqueIndices()	Most Bloom filters create unique IndexExtractors.
default IndexExtractor	CellExtractor.uniqueIndices()
default IndexExtractor	CountingBloomFilter.uniqueIndices()	The default implementation is a no-op since the counting bloom filter returns an unique IndexExtractor by default.
default IndexExtractor	IndexExtractor.uniqueIndices()	Creates an IndexExtractor comprising the unique indices for this extractor.
