Reference documentation and code samples for the Service Usage V1 API class Google::Protobuf::Mixin.
Declares an API Interface to be included in this interface. The including interface must redeclare all the methods from the included interface, but documentation and options are inherited as follows:
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.
Example of a simple mixin:
package google.acl.v1;
service AccessControl {
// Get the underlying ACL object.
rpc GetAcl(GetAclRequest) returns (Acl) {
option (google.api.http).get = "/v1/{resource=**}:getAcl";
}
}
package google.storage.v2;
service Storage {
rpc GetAcl(GetAclRequest) returns (Acl);
// Get a data record.
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";
}
...
}
