VoidEncoding

public VoidEncoding(EncodingId encodingId)

Method Details

withEncodingId

public VoidEncoding withEncodingId(EncodingId encodingId)

Description copied from interface: Encoding

Build an encoding that has the given EncodingId but is otherwise equivalent to this encoding.

If this encoding already has encodingId, then this method may (but is not required to) return this same instance.

Parameters:

encodingId - new encoding's EncodingId, or null for an anonymized encoding

Returns:

a version of this encoding with the given EncodingId

read

public Void read(ByteReader reader)

Description copied from interface: Encoding

Read a value from the given input.

Parameters:

reader - byte input

Returns:

field value (possibly null)

write

public void write(ByteWriter writer,
 Void value)

Description copied from interface: Encoding

Write a value to the given output.

Parameters:

writer - byte output

value - value to write (possibly null)

skip

public void skip(ByteReader reader)

Description copied from interface: Encoding

Read and discard a byte[] encoded value from the given input.

Parameters:

reader - byte input

convertNumber

protected Void convertNumber(Number value)

Specified by:

convertNumber in class PrimitiveEncoding<Void>
