#map(name, key_type, value_type, number, value_type_class = nil) ⇒ Object

Defines a new map field on this message type with the given key and value types, tag number, and type class (for message and enum value types). The key type must be :int32/:uint32/:int64/:uint64, :bool, or :string. The value type type must be a Ruby symbol (as accepted by FieldDescriptor#type=) and the type_class must be a string, if present (as accepted by FieldDescriptor#submsg_name=).
