AddUniverseDomainOption(ExperimentalTag, Options)

Creates an Options containing the UnifiedCredentialsOption and its corresponding UniverseDomainOption.

Uses the UnifiedCredentialsOption in options or ApplicationDefaultCredentials if UnifiedCredentialsOption is not found, and retrieves the universe_domain from those Credentials and sets the UniverseDomainOption to the result.

If the Metadata Server needs to be called, this function checks the options for the UniverseDomainRetryPolicyOption and UniverseDomainBackoffPolicyOption. If either policy option is not present a default policy is used for the corresponding policy option.

If everything succeeds, the Options returned contain both the UnifiedCredentialsOption and the UniverseDomainOption. If the RetryPolicy becomes exhausted or other errors are encountered, that Status is returned.

Parameters
Name Description
tag
options
Returns
Type Description
StatusOr< Options >

GetUniverseDomain(ExperimentalTag, Credentials const &, Options const &)

Interrogates the provided credentials for the universe_domain.

If the Metadata Server needs to be called, this function checks the options for the UniverseDomainRetryPolicyOption and UniverseDomainBackoffPolicyOption. If either policy option is not present a default policy is used for the corresponding policy option.

If successful the universe_domain value is returned, otherwise a Status indicating the error encountered is returned.

Parameters

Type Aliases

CommonOptionList

Alias Of: OptionList< EndpointOption, UserAgentProductsOption, LoggingComponentsOption, UserProjectOption, AuthorityOption, CustomHeadersOption >

A list of all the common options.

BackoffPolicy

Alias Of: ::google::cloud::internal::BackoffPolicy

The base class for backoff policies.

ExponentialBackoffPolicy

Alias Of: google::cloud::internal::ExponentialBackoffPolicy

A truncated exponential backoff policy with randomized periods.

UnifiedCredentialsOptionList

Alias Of: OptionList< AccessTokenLifetimeOption, CARootsFilePathOption, DelegatesOption, ScopesOption, LoggingComponentsOption, UnifiedCredentialsOption >

A list of options related to authentication.

BackgroundThreadsFactory

Alias Of: std::function< std::unique_ptr< BackgroundThreads >()>

GrpcOptionList

Alias Of: OptionList< GrpcCredentialOption, GrpcCompressionAlgorithmOption, GrpcNumChannelsOption, GrpcChannelArgumentsOption, GrpcChannelArgumentsNativeOption, GrpcTracingOptionsOption, GrpcBackgroundThreadPoolSizeOption, GrpcCompletionQueueOption, GrpcBackgroundThreadsFactoryOption >

A list of all the gRPC options.

IamUpdater

Alias Of: std::function< absl::optional< google::iam::v1::Policy >( google::iam::v1::Policy)>

Used in the SetIamPolicy() read-modify-write cycles where an etag helps prevent simultaneous updates of a policy from overwriting each other.

The updater is called with a recently fetched policy, and should either return an empty optional if no changes are required, or return a new policy to be set. In the latter case the updater should either (1) set the etag of the returned policy to that of the recently fetched policy (strongly suggested), or (2) not set the etag at all.

In case (1) if the etag does not match the existing policy (i.e., there has been an intermediate update), this update is dropped and a new cycle is initiated. In case (2) the existing policy is overwritten blindly.

optional

Alias Of: absl::optional< T >

Alias template for google::cloud::optional.

OptionList

Alias Of: internal::TypeList< T... >

A template to hold a list of "option" types.

This can be a useful way to create meaningful lists of options. For example, there could be a list containing all the gRPC options. Or a list of all ProductX options. This gives us a way to link to lists of options with doxygen, and to do some checking about what options a function may expect.

RestOptionList

Alias Of: ::google::cloud::OptionList< QuotaUserOption, RestTracingOptionsOption, ServerTimeoutOption, UserIpOption >

The complete list of options accepted by CurlRestClient
