Hello.
Please check my understanding of protobuf serialization and defaults.
I understand that if the value of a protobuf field is the same as the
default, then its not serialized.
Does that mean that if I have a field like
string foo = 1 [default=""];
And I explicitly set it to empty string:
bar.setFoo("");
or
bar.setFoo(fooString); // fooString=""
then I get the serialization savings?
Or do I need to do something like:
if ( foo != "" ) {
bar.setFoo(foo);
}
This is libprotobuf version 2.50, using Java
