    final int
    length()
    Serialize this record, if that has not been done already, and report the resulting wire size.
    protected abstract void
    serialize(DataOutputStream dos)
    The internal method used to serialize Data subclasses.
    private void
    setBytes()
    Rebuilds the bytes from the parsed fields.
    final byte[]
    toByteArray()
    Serialize this record, if that has not been done already, and return a copy of the result so callers cannot mutate the cached bytes.
    final void
    toOutputStream(DataOutputStream dos)
    Write the binary representation of this payload to the given DataOutputStream.
    final void
    toOutputStream(OutputStream outputStream)
    Write the binary representation to the given OutputStream.

    • serialize

      protected abstract void serialize(DataOutputStream dos) throws IOException
      The internal method used to serialize Data subclasses.
      Parameters:
      dos - the output stream to serialize to.
      Throws:
      IOException - if an I/O error occurs.

    • setBytes

      private void setBytes()
      Rebuilds the bytes from the parsed fields.

    • length

      public final int length()
      Serialize this record, if that has not been done already, and report the resulting wire size.
      Returns:
      the number of bytes this record serializes to

    • toOutputStream

      public final void toOutputStream(OutputStream outputStream) throws IOException
      Write the binary representation to the given OutputStream.
      Parameters:
      outputStream - the OutputStream to write to.
      Throws:
      IOException - if an I/O error occurs.

    • toOutputStream

      public final void toOutputStream(DataOutputStream dos) throws IOException
      Write the binary representation of this payload to the given DataOutputStream.
      Parameters:
      dos - the DataOutputStream to write to.

      IOException - if an I/O error occurs.

    • toByteArray

      public final byte[] toByteArray()
      Serialize this record, if that has not been done already, and return a copy of the result so callers cannot mutate the cached bytes.
      Returns:
      the binary representation as a byte array
