Methods

.configure

def self.configure() { |config| ... } -> Operations::Configuration

Configuration for the Workflows Operations API.

Yields
  • (config) — Configure the Operations client.
Yield Parameter
Returns

#cancel_operation

def cancel_operation(request, options = nil) -> ::Google::Protobuf::Empty
def 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.

Overloads 
def cancel_operation(request, options = nil) -> ::Google::Protobuf::Empty
Pass arguments to cancel_operation via a request object, either of type Longrunning::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) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional. 
def 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).
Parameter
  • name (::String) — The name of the operation resource to be cancelled.
Yields
  • (response, operation) — Access the result along with the RPC operation
Yield Parameters
Returns
Raises
  • (::Google::Cloud::Error) — if the RPC is aborted.
Example

Basic example

require "google/longrunning"

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

#configure

def configure() { |config| ... } -> Operations::Configuration

Configure the Workflows Operations 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 Operations.configure.

Yields
  • (config) — Configure the Operations client.
Yield Parameter
Returns

#delete_operation

def delete_operation(request, options = nil) -> ::Google::Protobuf::Empty
def delete_operation(name: nil) -> ::Google::Protobuf::Empty

Deletes a long-running operation. This method indicates that the client is no longer interested in the operation result. It does not cancel the operation. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED.

Overloads 
def delete_operation(request, options = nil) -> ::Google::Protobuf::Empty
Pass arguments to delete_operation via a request object, either of type Longrunning::DeleteOperationRequest or an equivalent Hash.

Parameter
  • name (::String) — The name of the operation resource to be deleted.
Yields
  • (response, operation) — Access the result along with the RPC operation
Yield Parameters
Returns

Example

Basic example

require "google/longrunning"

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

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

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

# The returned object is of type Gapic::Operation. You can use this
# object to check the status of an operation, cancel it, or wait
# for results. Here is how to block until completion:
result.wait_until_done! timeout: 60
if result.response?
  p result.response
else
  puts "Error!"
end

#initialize

def initialize() { |config| ... } -> Operations

Create a new Operations client object.

Yields
  • (config) — Configure the Client client.
Yield Parameter
Returns

#list_operations

def list_operations(request, options = nil) -> ::Gapic::PagedEnumerable<::Gapic::Operation>
def list_operations(name: nil, filter: nil, page_size: nil, page_token: nil) -> ::Gapic::PagedEnumerable<::Gapic::Operation>

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

NOTE: the name binding allows API services to override the binding to use different resource name schemes, such as users//operations. To override the binding, API services can add a binding such as "/v1/{name=users/}/operations" to their service configuration. For backwards compatibility, the default name includes the operations collection id, however overriding users must ensure the name binding is the parent resource, without the operations collection id.

Overloads 
def list_operations(request, options = nil) -> ::Gapic::PagedEnumerable<::Gapic::Operation>
Pass arguments to list_operations via a request object, either of type Longrunning::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) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional. 
def list_operations(name: nil, filter: nil, page_size: nil, page_token: nil) -> ::Gapic::PagedEnumerable<::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) — The name of the operation's parent resource.
  • filter (::String) — The standard list filter.
  • page_size (::Integer) — The standard list page size.
  • page_token (::String) — The standard list page token.
Yields
  • (response, operation) — Access the result along with the RPC operation
Yield Parameters
  • response (::Gapic::PagedEnumerable<::Gapic::Operation>)
  • operation (::GRPC::ActiveCall::Operation)
Returns
  • (::Gapic::PagedEnumerable<::Gapic::Operation>)
Raises
  • (::Google::Cloud::Error) — if the RPC is aborted.
Example

Basic example

require "google/longrunning"

# Create a client object. The client can be reused for multiple calls.
client = Google::Longrunning::Operations::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 all elements by calling #each, and the enumerable
# will lazily make API calls to fetch subsequent pages. Other
# methods are also available for managing paging directly.
result.each do |response|
  # Each element is of type ::Google::Longrunning::Operation.
  p response
end

#wait_operation

def wait_operation(request, options = nil) -> ::Gapic::Operation
def wait_operation(name: nil, timeout: nil) -> ::Gapic::Operation

Waits until the specified long-running operation is done or reaches at most a specified timeout, returning the latest state. If the operation is already done, the latest state is immediately returned. If the timeout specified is greater than the default HTTP/RPC timeout, the HTTP/RPC timeout is used. If the server does not support this method, it returns google.rpc.Code.UNIMPLEMENTED. Note that this method is on a best-effort basis. It may return the latest state before the specified timeout (including immediately), meaning even an immediate response is no guarantee that the operation is done.

Overloads 
def wait_operation(request, options = nil) -> ::Gapic::Operation
Pass arguments to wait_operation via a request object, either of type Longrunning::WaitOperationRequest or an equivalent Hash.
Parameters
  • request (::Google::Longrunning::WaitOperationRequest, ::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) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional. 
def wait_operation(name: nil, timeout: nil) -> ::Gapic::Operation
Pass arguments to wait_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) — The name of the operation resource to wait on.
  • timeout (::Google::Protobuf::Duration, ::Hash) — The maximum duration to wait before timing out. If left blank, the wait will be at most the time permitted by the underlying HTTP/RPC protocol. If RPC context deadline is also specified, the shorter one will be used.
Yields
  • (response, operation) — Access the result along with the RPC operation
Yield Parameters
  • response (::Gapic::Operation)
  • operation (::GRPC::ActiveCall::Operation)
Returns
  • (::Gapic::Operation)
Raises
  • (::Google::Cloud::Error) — if the RPC is aborted.
