Sorry but maybe my post is somehow confusing. I try to migrate my java
class into a protocal message class. Now I have a field like:
publiy MyClass {
Class anotherClass
}
I wonder how I should define that in a proto file (MyClassMessage).
Maybe like this:
message MyClass {
required string anotherClassName = 1;
}
Since I still have to use MyClass I just implement the writeObject()
and readObject() and use the the Class.forName():
private void writeObject(java.io.ObjectOutputStream out) throws
IOException {
Builder builder = MyClassMessage.MyClass.newBuilder();
builder.setAnotherClassName(anotherClassName.getName());
MyClassMessage.MyClass message = builder.build();
message.writeTo(out);
}
private void readObject(java.io.ObjectInputStream in)
throws ClassNotFoundException, IOException {
MyClassMessage.MyClass message =
MyClassMessage.MyClass.parseFrom(in);
anotherClassName= Class.forName(message.getAnotherClassName
());
}
