Re: [infinispan-dev] Protostream marshaller support for optional fields

Hi Galder, There's nothing special about optional fields. It is the required fields that are special: they do not allow null (in the read/write methods). If a field is optional in your protobuf schema you can write a null value and protostream will happily interpret that as a missing value and will not write any tag in the output protobuf stream. Reading a missing value will return a null. The required/optional status of a field is checked against the schema at runtime, so you cannot cheat :). None of the above holds true for a required field. Writes will only accept non-nulls (an exception is thrown immediately). Reads will always return a non-null value, so you can safely use a primitive-type-returning read method. If the input stream does not contain a required field (probably because the encoder that produced it was violating the schema) an exception is thrown.
