SegmentCodec

public SegmentCodec(PrimitiveCodec<B> primitiveCodec,
                    Compressor<B> compressor)

Method Detail

headerLength

public int headerLength()

The length of the segment header, excluding the 3-byte trailing CRC.

encode

public void encode(Segment<B> segment,
                   List<Object> out)

decodeHeader

public SegmentCodec.Header decodeHeader(B source)
                                 throws CrcMismatchException

Decodes a segment header and checks its CRC. It is assumed that the caller has already checked that there are enough bytes.

Throws:

CrcMismatchException

decode

public Segment<B> decode(SegmentCodec.Header header,
                         B source)
                  throws CrcMismatchException

Decodes the rest of a segment from a previously decoded header, and checks the payload's CRC. It is assumed that the caller has already checked that there are enough bytes.

Throws:

CrcMismatchException
