optional_field_style={default,accessors} (default: default)
Defines the style of the generated code for _optional_ fields only.
In the default style, optional fields translate into public mutable
Java fields, and the serialization process is as discussed in the
"IMPORTANT" section above. When set to 'accessors', each optional
field is encapsulated behind 4 accessors, namely get<fieldname>(),
set<fieldname>(), has<fieldname>() and clear<fieldname>() methods,
with the standard semantics. The hazzer's return value determines
whether a field is serialized, so this style is useful when you need
to serialize a field with the default value, or check if a field has
been explicitly set to its default value from the wire.
Required fields are still translated to one public mutable Java
field each, and repeated fields are still translated to arrays. No
accessors are generated for them.
optional_field_style=accessors cannot be used together with
java_nano_generate_has=true. If you need the 'has' flag for any
required field (you have no reason to), you can only use
java_nano_generate_has=true.
IMPORTANT: When using the 'accessor' style, ProGuard should always
be enabled with optimization (don't use -dontoptimize) and allowing
access modification (use -allowaccessmodification). This removes the
unused accessors and maybe inline the rest at the call sites,
reducing the final code size.
TODO(maxtroy): find ProGuard config that would work the best.
