An enum to be used to mark the essential (for polling) fields in an API-specific Operation object. A custom Operation object may contain many different fields, but only few of them are essential to conduct a successful polling process.
Constants
UNDEFINED
value: 0
Do not use.
NAME
value: 1
A field in an API-specific (custom) Operation object which carries the same
meaning as google.longrunning.Operation.name.
STATUS
value: 2
A field in an API-specific (custom) Operation object which carries the same
meaning as google.longrunning.Operation.done. If the annotated field is of
an enum type, annotated_field_name == EnumType.DONE semantics should be
equivalent to Operation.done == true. If the annotated field is of type
boolean, then it should follow the same semantics as Operation.done.
Otherwise, a non-empty value should be treated as Operation.done == true.
ERROR_CODE
value: 3
A field in an API-specific (custom) Operation object which carries the same
meaning as google.longrunning.Operation.error.code.
ERROR_MESSAGE
value: 4
A field in an API-specific (custom) Operation object which carries the same
meaning as google.longrunning.Operation.error.message.
