Hi,

  Is it true that has methods for optional fields in proto3 are removed 
from generated message ?
  If so, how can I decide if this field has been set or not ?
  
syntax ="proto3";

message Foo{

  int32 bar = 1;

}


// generated Foo.java

class Foo ... {

  int getBar();

  // the following method is missing
  // bool hasBar();

}


thanks 
wu
