Constructor Details

#initialize {|config| ... } ⇒ Client

Create a new QuotaController client object.

Examples:


# Create a client using the default configuration
client = ::Google::Cloud::ServiceControl::V1::QuotaController::Client.new

  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the QuotaController client.

Class Method Details

.configure {|config| ... } ⇒ Client::Configuration

Configure the QuotaController Client class.

See Configuration for a description of the configuration fields.

::Google::Cloud::ServiceControl::V1::QuotaController::Client.configure do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the Client client.

Instance Method Details

#allocate_quota(request, options = nil) ⇒ ::Google::Cloud::ServiceControl::V1::AllocateQuotaResponse #allocate_quota(service_name: nil, allocate_operation: nil, service_config_id: nil) ⇒ ::Google::Cloud::ServiceControl::V1::AllocateQuotaResponse

Attempts to allocate quota for the specified consumer. It should be called before the operation is executed.

This method requires the servicemanagement.services.quota permission on the specified service. For more information, see Cloud IAM.

NOTE: The client must fail-open on server errors INTERNAL, UNKNOWN, DEADLINE_EXCEEDED, and UNAVAILABLE. To ensure system reliability, the server may inject these errors to prohibit any hard dependency on the quota functionality.

Examples:

Basic example

require "google/cloud/service_control/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::ServiceControl::V1::QuotaController::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::ServiceControl::V1::AllocateQuotaRequest.new

# Call the allocate_quota method.
result = client.allocate_quota request

# The returned object is of type Google::Cloud::ServiceControl::V1::AllocateQuotaResponse.
p result

Overloads:

  • #allocate_quota(request, options = nil) ⇒ ::Google::Cloud::ServiceControl::V1::AllocateQuotaResponse

    Pass arguments to allocate_quota via a request object, either of type AllocateQuotaRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::ServiceControl::V1::AllocateQuotaRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #allocate_quota(service_name: nil, allocate_operation: nil, service_config_id: nil) ⇒ ::Google::Cloud::ServiceControl::V1::AllocateQuotaResponse

    Pass arguments to allocate_quota via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • service_name (::String) (defaults to: nil) —

      Name of the service as specified in the service configuration. For example, "pubsub.googleapis.com".

      See [google.api.Service][google.api.Service] for the definition of a service name.

    • allocate_operation (::Google::Cloud::ServiceControl::V1::QuotaOperation, ::Hash) (defaults to: nil) —

      Operation that describes the quota allocation.

    • service_config_id (::String) (defaults to: nil) —

      Specifies which version of service configuration should be used to process the request. If unspecified or no matching version can be found, the latest one will be used.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

#configure {|config| ... } ⇒ Client::Configuration

Configure the QuotaController Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.
