Method Detail

encodedClass

public Class<CellProtos.Cell> encodedClass()

Description copied from interface: DataType

Inform consumers over what type this DataType operates. Useful when working with bare DataType instances.

skip

public int skip(PositionedByteRange src)

Description copied from interface: DataType

Skip src's position forward over one encoded value.

Parameters:

src - the buffer containing the encoded value.

Returns:

number of bytes skipped.

decode

public CellProtos.Cell decode(PositionedByteRange src)

Description copied from interface: DataType

Read an instance of T from the buffer src.

Parameters:

src - the buffer containing the encoded value.

encode

public int encode(PositionedByteRange dst,
                  CellProtos.Cell val)

Description copied from interface: DataType

Write instance val into buffer dst.

Parameters:

dst - the buffer containing the encoded value.

val - the value to encode onto dst.

Returns:

number of bytes written.
