Google API Common Protos Client - Class FieldBehavior (4.8.3)

Version latest

• 4.8.3 (latest)
• 4.8.2

Reference documentation and code samples for the Google API Common Protos Client class FieldBehavior.

An indicator of the behavior of a given field (for example, that a field is required in requests, or given as output but ignored as input).

This does not change the behavior in protocol buffers itself; it only denotes the behavior and may affect how API tooling handles the field. Note: This enum may receive new values in the future.

Constants

FIELD_BEHAVIOR_UNSPECIFIED

Value: 0

Conventional default for enums. Do not use this.

Generated from protobuf enum FIELD_BEHAVIOR_UNSPECIFIED = 0;

OPTIONAL

Value: 1

Specifically denotes a field as optional.

While all fields in protocol buffers are optional, this may be specified for emphasis if appropriate.

Generated from protobuf enum OPTIONAL = 1;

REQUIRED

Value: 2

Denotes a field as required.

This indicates that the field must be provided as part of the request, and failure to do so will cause an error (usually INVALID_ARGUMENT).

Generated from protobuf enum REQUIRED = 2;

OUTPUT_ONLY

Value: 3

Denotes a field as output only.

This indicates that the field is provided in responses, but including the field in a request does nothing (the server must ignore it and must not throw an error as a result of the field's presence).

Generated from protobuf enum OUTPUT_ONLY = 3;

INPUT_ONLY

Value: 4

Denotes a field as input only.

This indicates that the field is provided in requests, and the corresponding field is not included in output.

Generated from protobuf enum INPUT_ONLY = 4;

IMMUTABLE

Value: 5

Denotes a field as immutable.

This indicates that the field may be set once in a request to create a resource, but may not be changed thereafter.

Generated from protobuf enum IMMUTABLE = 5;

UNORDERED_LIST

Value: 6

Denotes that a (repeated) field is an unordered list.

This indicates that the service may provide the elements of the list in any arbitrary order, rather than the order the user originally provided. Additionally, the list's order may or may not be stable.

Generated from protobuf enum UNORDERED_LIST = 6;

NON_EMPTY_DEFAULT

Value: 7

Denotes that this field returns a non-empty default value if not set.

This indicates that if the user provides the empty value in a request, a non-empty value will be returned. The user will not be aware of what non-empty value to expect.

Generated from protobuf enum NON_EMPTY_DEFAULT = 7;

IDENTIFIER

Value: 8

Denotes that the field in a resource (a message annotated with google.api.resource) is used in the resource name to uniquely identify the resource. For AIP-compliant APIs, this should only be applied to the name field on the resource.

This behavior should not be applied to references to other resources within the message. The identifier field of resources often have different field behavior depending on the request it is embedded in (e.g. for Create methods name is optional and unused, while for Update methods it is required). Instead of method-specific annotations, only IDENTIFIER is required.

Generated from protobuf enum IDENTIFIER = 8;
