@Target({METHOD,CONSTRUCTOR})
@Retention(RUNTIME)
@Documented
public @interface ProtoFactory
```
Designates the constructor or static method that is used for creating instances of a message class. Cannot be used with instance methods. The method/constructor must not be private and must have a signature containing the exact same number of parameters as the protobuf fields. Each parameter must correspond to a protobuf field, named identically to the name of the Java field/property used for declaring the protobuf field and the type of each parameter must also be identical to the type of the corresponding field/property. The ordering of parameters versus fields is not relevant because they are matched by name (not by position). A single constructor or static method is allowed to have this annotation in a ProtoStream marshallable class. This annotation is not inherited, occurrences in superclass/superinterfaces are ignored for this class.
This annotation is meant to support creation of immutable messages. When used in a class, all protobuf fields must be declared with annotations on instance fields or getter methods. Setter are not allowed to be annotated.
Classes that do not have a constructor or static method annotated with this annotation must at least have an accessible no-argument constructor to be used for instantiating the class.
NOTE This annotation can be processed at runtime only if parameter name debug information was emitted by the compiler, ie. the compiler was invoked with the -parameters flag. Usage of this annotation at compile time is possible regardless of that.
