Overview

REST client for the Operations service.

Manages long-running operations with an API service.

When an API method normally takes long time to complete, it can be designed to return Operation to the client, and the client can use this interface to receive the real response asynchronously by polling the operation resource, or pass the operation resource to another API (such as Pub/Sub API) to receive the response. Any API service that returns long-running operations should implement the Operations interface so developers can have a consistent client experience.

Instance Method Details

#cancel_operation(request, options = nil) ⇒ ::Google::Protobuf::Empty #cancel_operation(name: nil) ⇒ ::Google::Protobuf::Empty

Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED. Clients can use Operations.GetOperation or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an Operation.error value with a google.rpc.Status.code of 1, corresponding to Code.CANCELLED.

Examples:

Basic example

require "google/longrunning"

# Create a client object. The client can be reused for multiple calls.
client = Google::Longrunning::Operations::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Longrunning::CancelOperationRequest.new

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

# The returned object is of type Google::Protobuf::Empty.
p result

Overloads:

  • #cancel_operation(request, options = nil) ⇒ ::Google::Protobuf::Empty

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

    Parameters:

    • request (::Google::Longrunning::CancelOperationRequest, ::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.

  • #cancel_operation(name: nil) ⇒ ::Google::Protobuf::Empty

    Pass arguments to cancel_operation 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:

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

      The name of the operation resource to be cancelled.

Yields:

  • (result, operation) —

    Access the result along with the TransportOperation object

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.

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

Configure the Operations 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:

    Configure the Client client.

#delete_operation(request, options = nil) ⇒ ::Google::Protobuf::Empty #delete_operation(name: nil) ⇒ ::Google::Protobuf::Empty

Examples:

Basic example

require "google/longrunning"

# Create a client object. The client can be reused for multiple calls.
client = Google::Longrunning::Operations::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Longrunning::DeleteOperationRequest.new

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

# The returned object is of type Google::Protobuf::Empty.
p result

Overloads:

  • #delete_operation(request, options = nil) ⇒ ::Google::Protobuf::Empty

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

    Parameters:

    • request (::Google::Longrunning::DeleteOperationRequest, ::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.

  • #delete_operation(name: nil) ⇒ ::Google::Protobuf::Empty

    Pass arguments to delete_operation 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).

#list_operations(request, options = nil) ⇒ ::Gapic::Operation #list_operations(name: nil, filter: nil, page_size: nil, page_token: nil, return_partial_success: nil) ⇒ ::Gapic::Operation

Lists operations that match the specified filter in the request. If the server doesn't support this method, it returns UNIMPLEMENTED.

Examples:

Basic example

require "google/longrunning"

# Create a client object. The client can be reused for multiple calls.
client = Google::Longrunning::Operations::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Longrunning::ListOperationsRequest.new

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

# The returned object is of type Gapic::PagedEnumerable. You can iterate
# over elements, and API calls will be issued to fetch pages as needed.
result.each do |item|
  # Each element is of type ::Google::Longrunning::Operation.
  p item
end

Overloads:

  • #list_operations(request, options = nil) ⇒ ::Gapic::Operation

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

    Parameters:

    • request (::Google::Longrunning::ListOperationsRequest, ::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.

  • #list_operations(name: nil, filter: nil, page_size: nil, page_token: nil, return_partial_success: nil) ⇒ ::Gapic::Operation

    Pass arguments to list_operations 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:

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

      The name of the operation's parent resource.

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

      The standard list filter.

    • page_size (::Integer) (defaults to: nil) —

      The standard list page size.

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

      The standard list page token.

    • return_partial_success (::Boolean) (defaults to: nil) —

      When set to true, operations that are reachable are returned as normal, and those that are unreachable are returned in the [ListOperationsResponse.unreachable] field.

      This can only be true when reading across collections e.g. when parent is set to "projects/example/locations/-".

      This field is not by default supported and will result in an UNIMPLEMENTED error if set unless explicitly documented otherwise in service or product specific documentation.

Yields:

  • (result, operation) —

    Access the result along with the TransportOperation object

Yield Parameters:

  • result (::Gapic::Operation)
  • operation (::Gapic::Rest::TransportOperation)

Returns:

  • (::Gapic::Operation)

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.
