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 inheriting 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"; } ... }Protobuf type

newInstance
Description copied from class:GeneratedMessageV3
Creates a new instance of this message type. Overridden in the generated code.- Overrides:

-
internalGetFieldAccessorTable
Description copied from class:GeneratedMessageV3
Get the FieldAccessorTable for this type. We can't have the message class pass this in to the constructor because of bootstrapping trouble with DescriptorProtos.- Specified by:
internalGetFieldAccessorTable
in classGeneratedMessageV3
-

Serializes the message and writes it tooutput
. This does not flush or close the stream.- Specified by:
writeTo
in interfaceMessageLite
- Overrides:
writeTo
in classGeneratedMessageV3
- Throws:
IOException
-
getSerializedSize
public int getSerializedSize()Description copied from interface:MessageLite
Get the number of bytes required to encode this message. The result is only computed on the first call and memoized after that. If this message requires more than Integer.MAX_VALUE bytes to encode, the return value will be smaller than the actual number of bytes required and might be negative.- Specified by:
getSerializedSize
in interfaceMessageLite
- Overrides:
getSerializedSize
in classGeneratedMessageV3
-
equals
Description copied from interface:Message
Compares the specified object with this message for equality. Returnstrue
if the given object is a message of the same type (as defined bygetDescriptorForType()
) and has identical values for all of its fields. Subclasses must implement this; inheritingObject.equals()
is incorrect.- Specified by:
equals
in interfaceMessage
- Overrides:
equals
in classAbstractMessage
- Parameters:
obj
- object to be compared for equality with this message- Returns:
true
if the specified object is equal to this message
-
hashCode
public int hashCode()Description copied from interface:Message
Returns the hash code value for this message. The hash code of a message should mix the message's type (object identity of the descriptor) with its contents (known and unknown field values). Subclasses must implement this; inheritingObject.hashCode()
is incorrect.- Specified by:
hashCode
in interfaceMessage
- Overrides:
hashCode
in classAbstractMessage
- Returns:
- the hash code value for this message

getDefaultInstanceForType
Description copied from interface:MessageLiteOrBuilder
Get an instance of the type with no fields set. Because no fields are set, all getters for singular fields will return default values and repeated fields will appear empty. This may or may not be a singleton. This differs from thegetDefaultInstance()
method of generated message classes in that this method is an abstract method of theMessageLite
interface whereasgetDefaultInstance()
is a static method of a specific class. They return the same thing.- Specified by:
