                         OutputStream outStream,
                         Coder.Context context)
                  throws IOException

      Description copied from interface: Coder
      Encodes the given value of type T onto the given output stream in the given context.

      Throws:

      IOException - if writing to the OutputStream fails for some reason

      CoderException - if the value could not be encoded for some reason

    • decode

      public TimestampedValue<T> decode(InputStream inStream,
                                        Coder.Context context)
                                 throws IOException

      Description copied from interface: Coder
      Decodes a value of type T from the given input stream in the given context. Returns the decoded value.

      Throws:

      IOException - if reading from the InputStream fails for some reason

      CoderException - if the value could not be decoded for some reason

    • verifyDeterministic

      public void verifyDeterministic()
                               throws Coder.NonDeterministicException

      Description copied from interface: Coder
      Throw Coder.NonDeterministicException if the coding is not deterministic.

      In order for a Coder to be considered deterministic, the following must be true:

      • two values that compare as equal (via Object.equals() or Comparable.compareTo(), if supported) have the same encoding.
      • the Coder always produces a canonical encoding, which is the same for an instance of an object even if produced on different computers at different times.

      Throws:

      Coder.NonDeterministicException - if this coder is not deterministic.

    • getCoderArguments

      public List<? extends Coder<?>> getCoderArguments()

      Description copied from interface: Coder
      If this is a Coder for a parameterized type, returns the list of Coders being used for each of the parameters, or returns null if this cannot be done or this is not a parameterized type.
