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.
