Constructor Detail

StringEncoder

public StringEncoder()

Create a new StringEncoder.

Method Detail

writeTo

public void writeTo(Tag tag,
                    Object value,
                    byte[] b,
                    int offset)

Description copied from interface: Encoder

Encode a value to a byte array.

Specified by:

writeTo in interface Encoder

Parameters:

tag - The tag of the value to encode.

value - The value to encode.

b - The byte array to encode the value to.

offset - The offset within b to begin encoding from.

readFrom

public Object readFrom(Tag tag,
                       byte[] b,
                       int offset,
                       int length)

Description copied from interface: Encoder

Decode a value from a byte array.

Specified by:

readFrom in interface Encoder

Parameters:

tag - The tag of the value to decode.

b - The byte array to decode the value from.

offset - The offset in b to begin decoding from.

length - The length of the value to decode.

Returns:

The value object.

getValueLength

public int getValueLength(Tag tag,
                          Object value)

Description copied from interface: Encoder

Calculate the length, in bytes, that the value will encode as. The value returned from this method must exactly match the number of bytes that writeTo will attempt to encode to a byte array.

Specified by:

getValueLength in interface Encoder

Parameters:

tag - The tag of the value to get the length for.

value - The value to get the length for.

Returns:

The length value will encode to in bytes.
