Description

Class Summary

ChunksIntEncoder	An IntEncoder which encodes values in chunks.
DGapIntDecoder	An IntDecoder which wraps another decoder and reverts the d-gap that was encoded by DGapIntEncoder.
DGapIntEncoder	An IntEncoderFilter which encodes the gap between the given values, rather than the values themselves.
DGapVInt8IntDecoder	Decodes values encoded by DGapVInt8IntDecoder.
DGapVInt8IntEncoder	An IntEncoder which implements variable length encoding for the gap between values.
EightFlagsIntDecoder	Decodes values encoded with EightFlagsIntEncoder.
EightFlagsIntEncoder	A ChunksIntEncoder which encodes data in chunks of 8.
FourFlagsIntDecoder	Decodes values encoded with FourFlagsIntEncoder.
FourFlagsIntEncoder	A ChunksIntEncoder which encodes values in chunks of 4.
IntDecoder	Decodes integers from a set BytesRef.
IntEncoder	Encodes integers to a set BytesRef.
IntEncoderFilter	An abstract implementation of IntEncoder which wraps another encoder.
NOnesIntDecoder	Decodes values encoded encoded with NOnesIntEncoder.
NOnesIntEncoder	A variation of FourFlagsIntEncoder which translates the data as follows: Values ≥ 2 are trnalsated to value+1 (2 ⇒ 3, 3 ⇒ 4 and so forth).
SimpleIntDecoder	Decodes values encoded with SimpleIntEncoder.
SimpleIntEncoder	A simple IntEncoder, writing an integer as 4 raw bytes.
SortingIntEncoder	An IntEncoderFilter which sorts the values to encode in ascending order before encoding them.
UniqueValuesIntEncoder	An IntEncoderFilter which ensures only unique values are encoded.
VInt8IntDecoder	Decodes values encoded by VInt8IntEncoder.
VInt8IntEncoder	An IntEncoder which implements variable length encoding.
