Lets say I have test.proto file:
syntax = "proto3";
option java_package = "testing";
option java_outer_classname = "Test_v1";
import "google/protobuf/wrappers.proto";
message TestMessage {
.google.protobuf.Int32Value integerField = 1;
}
If I compile (using protoc v3.5.0) it to c# code I will get nullable type
properties:
public int? IntegerField {
get { return integerField_; }
set { integerField_ = value; }
}
But if I compile it to Java code, fields will be of well-known type:
public Builder setIntegerField(com.google.protobuf.Int32Value value) {
if (integerFieldBuilder_ == null) {
if (value == null) {
throw new NullPointerException();
}
integerField_ = value;
onChanged();
} else {
integerFieldBuilder_.setMessage(value);
}
I am moving project from proto2 to proto3 so I would like to avoid using
well-known types, because it will require a lot of work to change related
code. With c# projects I will not require to modify anything but in Java I
will need to do as in the following example:
TestMessage.Builder builder = TestMessage.newBuilder();
builder.setIntegerField(5); //<-- instead of this (with proto2)
builder.setIntegerField(Int32Value.newBuilder().setValue(5)); //<-- I
will need to change to something like this (with proto3)
Is there a way to compile proto file to Java so setters would accept
primitive classes/wrappers (String, Integer, etc.) as parameters?
