Class ByteBufferToHexFormatJsonEncoder

  • All Implemented Interfaces:
    java.io.Flushable, org.apache.avro.io.parsing.Parser.ActionHandler
    public class ByteBufferToHexFormatJsonEncoder
extends org.apache.avro.io.JsonEncoder
    This class overrides JsonEncoder.writeBytes(byte[], int, int), in order to convert all bytes schema data to hexadecimal strings in the output stream, since hexadecimal strings are more readable. This should be used in tooling only.
