| 122 | +// - If after comment and whitespace stripping, the documentation |

| 127 | +// visibility) which is not set in the redeclared method will be |
| 128 | +// inherited. |

| 131 | +// modified as follows. Any version prefix will be replaced by the |
| 132 | +// version of the including API plus the [root][] path if specified. |

| 135 | +// |

| 138 | +// // Get the underlying ACL object. |

| 150 | +// option (google.api.http).get = "/v2/{resource=**}"; |
| 151 | +// } |
| 152 | +// } |
| 153 | +// |
| 154 | +// Example of a mixin configuration: |
| 155 | +// |
| 156 | +// apis: |
| 157 | +// - name: google.storage.v2.Storage |
| 158 | +// mixins: |
| 159 | +// - name: google.acl.v1.AccessControl |
| 160 | +// |
| 161 | +// The mixin construct implies that all methods in `AccessControl` are |
| 162 | +// also declared with same name and request/response types in |
| 163 | +// `Storage`. A documentation generator or annotation processor will |
| 164 | +// see the effective `Storage.GetAcl` method after inherting |
| 165 | +// documentation and annotations as follows: |
| 166 | +// |
| 167 | +// service Storage { |
| 168 | +// // Get the underlying ACL object. |
| 169 | +// rpc GetAcl(GetAclRequest) returns (Acl) { |
| 170 | +// option (google.api.http).get = "/v2/{resource=**}:getAcl"; |
| 171 | +// } |
| 172 | +// ... |
| 173 | +// } |
| 174 | +// |
| 175 | +// Note how the version in the path pattern changed from `v1` to `v2`. |
| 176 | +// |
| 177 | +// If the `root` field in the mixin is specified, it should be a |
| 178 | +// relative path under which inherited HTTP paths are placed. Example: |
| 179 | +// |
| 180 | +// apis: |
| 181 | +// - name: google.storage.v2.Storage |
| 182 | +// mixins: |
| 183 | +// - name: google.acl.v1.AccessControl |
| 184 | +// root: acls |
| 185 | +// |
| 186 | +// This implies the following inherited HTTP annotation: |
| 187 | +// |
| 188 | +// service Storage { |
| 189 | +// // Get the underlying ACL object. |
| 190 | +// rpc GetAcl(GetAclRequest) returns (Acl) { |
