 |   // In client libraries, each proto RPC corresponds to one or more methods | 
 |   // which the end user is able to call, and calls the underlying RPC. | 
 |   // Normally, this method receives a single argument (a struct or instance | 
 |   // corresponding to the RPC request object). Defining this field will | 
 |   // add one or more overloads providing flattened or simpler method signatures | 
 |   // in some languages. | 
 |   // | 
 |   // The fields on the method signature are provided as a comma-separated | 
 |   // string. | 
 |   // | 
 |   // For example, the proto RPC and annotation: | 
 |   // | 
 |   //   rpc CreateSubscription(CreateSubscriptionRequest) | 
 |   //       returns (Subscription) { | 
 |   //     option (google.api.method_signature) = "name,topic"; | 
 |   //   } | 
 |   // | 
 |   // Would add the following Java overload (in addition to the method accepting | 
 |   // the request object): | 
 |   // | 
 |   //   public final Subscription createSubscription(String name, String topic) | 
 |   // | 
 |   // The following backwards-compatibility guidelines apply: | 
 |   // | 
 |   //   * Adding this annotation to an unannotated method is backwards | 
 |   //     compatible. | 
 |   //   * Adding this annotation to a method which already has existing | 
 |   //     method signature annotations is backwards compatible if and only if | 
 |   //     the new method signature annotation is last in the sequence. | 
 |   //   * Modifying or removing an existing method signature annotation is | 
 |   //     a breaking change. | 
 |   //   * Re-ordering existing method signature annotations is a breaking | 
 |   //     change. |
