Method Detail

encodedLength

public int encodedLength(String 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<String> encodedClass()

Description copied from interface: DataType

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

decode

public String 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,
                  String 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.
