                              throws ConvertNotSupportException

覆盖:

doConvertToTiDBType 在类中 BytesType

抛出:

ConvertNotSupportException

getName

public String getName()

覆盖:

getName 在类中 BytesType

decodeNotNull

protected Object decodeNotNull(int flag,
                               CodecDataInput cdi)

覆盖:

decodeNotNull 在类中 BytesType

encodeKey

protected void encodeKey(CodecDataOutput cdo,
                         Object value)

覆盖:

encodeKey 在类中 BytesType
