public static final class Mixin.Builder extends GeneratedMessage.Builder<Mixin.Builder> implements MixinOrBuilder
google.protobuf.Mixin
Declares an API to be included in this API. The including API must
redeclare all the methods from the included API, 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 API 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 {
// (-- see AccessControl.GetAcl --)
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";
}
...
}
| Modifier and Type | Method and Description |
|---|---|
Mixin |
build()

Called by the initialization and clear code paths to allow subclasses to
reset any of their builtin fields back to the initial values.
|

Message.Builderother into the message being built. other must
have the exact same type as this (i.e.
getDescriptorForType() == other.getDescriptorForType()).
Merging occurs as follows. For each field:other,
then other's value overwrites the value in this message.other,
it is merged into the corresponding sub-message of this message
using the same merging rules.other are concatenated
with the elements in this message.
* For oneof groups, if the other message has one of the fields set,
the group of this message is cleared and replaced by the field
of the other message, so that the oneof constraint is preserved.
