Method Detail

encodedLength

public int encodedLength(byte[] val)

Description copied from interface: DataType

Inform consumers how long the encoded byte[] will be.

Parameters:

val - The value to check.

Returns:

the number of bytes required to encode val.a

encodedClass

public Class<byte[]> encodedClass()

Description copied from interface: DataType

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

decode

public byte[] 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,
                  byte[] 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.

encode

public int encode(PositionedByteRange dst,
                  byte[] val,
                  int voff,
                  int vlen)

Write a subset of val to buff.
