|

// - If after comment and whitespace stripping, the documentation

|
// string of the redeclared method is empty, it will be inherited

// from the original method.

|
|
// - Each annotation belonging to the service config (http,
|
|
// visibility) which is not set in the redeclared method will be
|
|
// inherited.
|
|
//
|
|
// - If an http annotation is inherited, the path pattern will be
|
|
// modified as follows. Any version prefix will be replaced by the

|
// version of the including interface plus the [root][] path if
|
|
// specified.
|
|

|

|
|
//
|
|
// package google.acl.v1;

|
// service AccessControl {
|
|
// // Get the underlying ACL object.
|

// rpc GetAcl(GetAclRequest) returns (Acl) {

|
// rpc GetData(GetDataRequest) returns (Data) {
|
|
// option (google.api.http).get = "/v2/{resource=**}";
|
|
// }

// }
|

//
|

// Example of a mixin configuration:
|
|
//
|
|
// apis:
|
|
// - name: google.storage.v2.Storage
|
|
// mixins:
|
|
// - name: google.acl.v1.AccessControl
|
|
//
|
|
// The mixin construct implies that all methods in `AccessControl` are
|
|
// also declared with same name and request/response types in
|
|
// `Storage`. A documentation generator or annotation processor will
|
|
// see the effective `Storage.GetAcl` method after inherting
|
|
// documentation and annotations as follows:
|
|
//
|
|
// service Storage {
|
|
// // Get the underlying ACL object.
|
|
// rpc GetAcl(GetAclRequest) returns (Acl) {
|
|
// option (google.api.http).get = "/v2/{resource=**}:getAcl";
|
|
// }
|
|
// ...
|
|
// }
|
|
//
|
|
// Note how the version in the path pattern changed from `v1` to `v2`.
|
|
//
|
|
// If the `root` field in the mixin is specified, it should be a
|
|
// relative path under which inherited HTTP paths are placed. Example:
|
|
//
|
|
// apis:
|
|
// - name: google.storage.v2.Storage
|
|
// mixins:
|
|
// - name: google.acl.v1.AccessControl
|
|
// root: acls
|
|
//
|
|
// This implies the following inherited HTTP annotation:
|
|
//
|
|
// service Storage {
|
|
// // Get the underlying ACL object.
|
|
// rpc GetAcl(GetAclRequest) returns (Acl) {
|
|
// option (google.api.http).get = "/v2/acls/{resource=**}:getAcl";
