Reference documentation and code samples for the Cloud Scheduler V1 API module Google::Api::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.
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.
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).
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).
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.
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.
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.
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.
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.
