public void encode(TableRow value, java.io.OutputStream outStream) throws java.io.IOException
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<TableRow>java.io.IOException - if writing to the OutputStream fails for some reasonCoderException - if the value could not be encoded for some reasonpublic void encode(TableRow value, java.io.OutputStream outStream, Coder.Context context) throws java.io.IOException

throws Coder.NonDeterministicException
Coder.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.
Unless overridden, does not throw. An AtomicCoder is presumed to be deterministic
verifyDeterministic in class AtomicCoder<TableRow>NonDeterministicException - always. A TableRow can hold arbitrary Object
instances, which makes the encoding non-deterministic.Coder.NonDeterministicException - if this coder is not deterministic.public TypeDescriptor<TableRow> getEncodedTypeDescriptor()
