Interface Summary
Interface	Description
BloomFilter.Strategy	A strategy to translate T instances, to `numHashFunctions` bit indexes.
Funnel<T>	An object which can send data from an object of type `T` into a `PrimitiveSink`.
Hasher	A `PrimitiveSink` that can compute a hash code after reading the input.
HashFunction	A hash function is a collision-averse pure function that maps an arbitrary block of data to a number called a hash code.
PrimitiveSink	An object which can receive a stream of primitive values.

Class Summary
Class	Description
AbstractByteHasher	Abstract `Hasher` that handles converting primitives to bytes using a scratch `ByteBuffer` and streams all bytes to a sink to compute the hash.
AbstractCompositeHashFunction	An abstract composition of multiple hash functions.
AbstractHasher	An abstract hasher, implementing `AbstractHasher.putBoolean(boolean)`, `AbstractHasher.putDouble(double)`, `AbstractHasher.putFloat(float)`, `AbstractHasher.putUnencodedChars(CharSequence)`, and `AbstractHasher.putString(CharSequence, Charset)` as prescribed by `Hasher`.
AbstractNonStreamingHashFunction	Skeleton implementation of `HashFunction`, appropriate for non-streaming algorithms.
AbstractNonStreamingHashFunction.ExposedByteArrayOutputStream
AbstractStreamingHashFunction	Skeleton implementation of `HashFunction`.
AbstractStreamingHashFunction.AbstractStreamingHasher	A convenience base class for implementors of `Hasher`; handles accumulating data until an entire "chunk" (of implementation-dependent length) is ready to be hashed.
BloomFilter<T>	A Bloom filter for instances of `T`.
BloomFilter.SerialForm<T>
BloomFilterStrategies.BitArray
