CoderT onto the given output stream. Multiple elements can
be encoded next to each other on the output stream, each coder should encode information to
know how many bytes to read when decoding. A common approach is to prefix the encoding with the
element's encoded length.encode in class Coder<WindowedValue<T>>CoderException - if the value could not be encoded for some reasonjava.io.IOException - if writing to the OutputStream fails for some reasonpublic void encode(WindowedValue<T> windowedElem, java.io.OutputStream outStream, Coder.Context context) throws CoderException, java.io.IOException

throws Coder.NonDeterministicException
CoderCoder.NonDeterministicException if the coding is not deterministic.
In order for a Coder to be considered deterministic, the following must be true:
Object.equals() or Comparable.compareTo(), if supported) have the same encoding.
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.

CoderElementByteSizeObserver about the byte size of the encoded value using
this Coder.
Not intended to be called by user code, but instead by PipelineRunner
implementations.
By default, this notifies observer about the byte size of the encoded value using
this coder as returned by Coder.getEncodedElementByteSize(T).

Coder for a parameterized type, returns the list of Coders being
used for each of the parameters in the same order they appear within the parameterized type's
type signature. If this cannot be done, or this Coder does not encode/decode a
parameterized type, returns the empty list..getCoderArguments in class Coder<WindowedValue<T>>valueCoder of this WindowedValues.FullWindowedValueCoder.public java.util.List<? extends Coder<?>> getComponents()
StructuredCoderCoders that are components of this Coder.
The default components will be equal to the value returned by Coder.getCoderArguments().
