public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

readExternal

public void readExternal(ObjectInput in)
                  throws IOException

hasCustomCoders

protected boolean hasCustomCoders()

Returns true iff an instance supports the MessageEncoder.encode(D) and MessageDecoder.decode(java.io.InputStream) operations. Should only be used by SpecificDatumReader/Writer to selectively use customEncode(org.apache.avro.io.Encoder) and customDecode(org.apache.avro.io.ResolvingDecoder) to optimize the (de)serialization of values.

customEncode

                  throws IOException

Throws:

IOException

customDecode

public void customDecode(ResolvingDecoder in)
                  throws IOException

Throws:

IOException
