Google API Core Client - Class OperationResponse (1.36.1)

Reference documentation and code samples for the Google API Core Client class OperationResponse.

Response object from a long running API method.

The OperationResponse object is returned by API methods that perform a long running operation. It provides methods that can be used to poll the status of the operation, retrieve the results, and cancel the operation.

To support a long running operation, the server must implement the Operations API, which is used by the OperationResponse object. If more control is required, it is possible to make calls against the Operations API directly instead of via the OperationResponse object using an Operations Client instance.

Namespace

Google \ ApiCore

Methods

__construct

OperationResponse constructor.

Parameters
Name
Description
operationName
string
operationsClient
object
options
array

Optional. Options for configuring the operation response object.

↳ operationReturnType
string

The return type of the longrunning operation.

↳ metadataReturnType
string

The type of the metadata returned in the operation response.

↳ initialPollDelayMillis
int

The initial polling interval to use, in milliseconds.

↳ pollDelayMultiplier
int

Multiplier applied to the polling interval on each retry.

↳ maxPollDelayMillis
int

The maximum polling interval to use, in milliseconds.

↳ totalPollTimeoutMillis
int

The maximum amount of time to continue polling.

↳ lastProtoResponse
object

A response already received from the server.

↳ getOperationMethod
string

The method on $operationsClient to get the operation.

↳ cancelOperationMethod
string

The method on $operationsClient to cancel the operation.

↳ deleteOperationMethod
string

The method on $operationsClient to delete the operation.

↳ operationStatusMethod
string

The method on the operation to get the status.

↳ operationStatusDoneValue
string

The method on the operation to determine if the status is done.

↳ additionalOperationArguments
array

Additional arguments to pass to $operationsClient methods.

↳ operationErrorCodeMethod
string

The method on the operation to get the error code

↳ operationErrorMessageMethod
string

The method on the operation to get the error status

isDone

Check whether the operation has completed.

Returns
Type
Description
bool

operationSucceeded

Check whether the operation completed successfully. If the operation is not complete, or if the operation failed, return false.

Returns
Type
Description
bool

operationFailed

Check whether the operation failed. If the operation is not complete, or if the operation succeeded, return false.

Returns
Type
Description
bool

getName

Get the formatted name of the operation

Returns
Type
Description
string
The formatted name of the operation

pollUntilComplete

Poll the server in a loop until the operation is complete.

Return true if the operation completed, otherwise return false. If the $options['totalPollTimeoutMillis'] setting is not set (or set <= 0) then pollUntilComplete will continue polling until the operation completes, and therefore will always return true.

Parameters
Name
Description
options
array

Options for configuring the polling behaviour.

↳ initialPollDelayMillis
int

The initial polling interval to use, in milliseconds.

↳ pollDelayMultiplier
int

Multiplier applied to the polling interval on each retry.

↳ maxPollDelayMillis
int

The maximum polling interval to use, in milliseconds.

↳ totalPollTimeoutMillis
int

The maximum amount of time to continue polling, in milliseconds.

Returns
Type
Description
bool
Indicates if the operation completed.

reload

Reload the status of the operation with a request to the service.

getResult

Return the result of the operation. If operationSucceeded() is false, return null.

Returns
Type
Description
mixed|null
The result of the operation, or null if operationSucceeded() is false

getError

If the operation failed, return the status. If operationFailed() is false, return null.

Returns
Type
Description
The status of the operation in case of failure, or null if operationFailed() is false.

getDescriptorOptions

Get an array containing the values of 'operationReturnType', 'metadataReturnType', and the polling options initialPollDelayMillis , pollDelayMultiplier , maxPollDelayMillis , and totalPollTimeoutMillis . The array can be passed as the $options argument to the constructor when creating another OperationResponse object.

Returns
Type
Description
array

getLastProtoResponse

Returns
Type
Description
The last Operation object received from the server.

getOperationsClient

Returns
Type
Description
object
The OperationsClient object used to make requests to the operations API.

cancel

Cancel the long-running operation.

For operations of type Google\LongRunning\Operation, this method 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 will throw an ApiException with code \Google\Rpc\Code::UNIMPLEMENTED. Clients can continue to use reload and pollUntilComplete 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 a getError() value with a \Google\Rpc\Status code of 1, corresponding to \Google\Rpc\Code::CANCELLED.

delete

Delete the long-running operation.

For operations of type Google\LongRunning\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 will throw an ApiException with code \Google\Rpc\Code::UNIMPLEMENTED.

Get the metadata returned with the last proto response. If a metadata type was provided, then the return value will be of that type - otherwise, the return value will be of type Any. If no metadata object is available, returns null.

Returns
Type
Description
mixed
The metadata returned from the server in the last response.
