OperationsClient
class OperationsClient extends OperationsGapicClient (View source)
{@inheritdoc}
Traits
Common functions used to work with various clients.
Provides basic array helper methods.
Provides helper methods for gRPC support.
Constants
| SERVICE_NAME |
The name of the service. |
| DEFAULT_SERVICE_PORT |
The default port of the service. |
| CODEGEN_NAME |
The name of the code generator, to be included in the agent header. |
Methods
Initiates an orderly shutdown in which preexisting calls continue but new calls are immediately cancelled.
Gets the latest state of a long-running operation. Clients can use this method to poll the operation result at intervals as recommended by the API service.
Lists operations that match the specified filter in the request. If the
server doesn't support this method, it returns UNIMPLEMENTED.
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][google.longrunning.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][google.longrunning.Operation.error] value with a [google.rpc.Status.code][google.rpc.Status.code] of 1,
corresponding to Code.CANCELLED.
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.

Operation
getOperation(string $name, array $optionalArgs = [])
Gets the latest state of a long-running operation. Clients can use this method to poll the operation result at intervals as recommended by the API service.
Sample code:
$options = [
'apiEndpoint' => 'my-service-address',
'scopes' => ['my-service-scope'],
];
$operationsClient = new OperationsClient($options);
try {
$name = '';
$response = $operationsClient->getOperation($name);
} finally {
if (isset($operationsClient)) {
$operationsClient->close();
}
}
PagedListResponse
listOperations(string $name, string $filter, array $optionalArgs = [])
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 below allows API services to override the binding
to use different resource name schemes, such as users/*/operations.
Sample code:
$options = [
'apiEndpoint' => 'my-service-address',
'scopes' => ['my-service-scope'],
];
$operationsClient = new OperationsClient($options);
try {
$name = '';
$filter = '';
// Iterate through all elements
$pagedResponse = $operationsClient->listOperations($name, $filter);
foreach ($pagedResponse->iterateAllElements() as $element) {
// doSomethingWith($element);
}
// OR iterate over pages of elements
$pagedResponse = $operationsClient->listOperations($name, $filter);
foreach ($pagedResponse->iteratePages() as $page) {
foreach ($page as $element) {
// doSomethingWith($element);
}
}
} finally {
if (isset($operationsClient)) {
$operationsClient->close();
}
}
cancelOperation(string $name, array $optionalArgs = [])
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][google.longrunning.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][google.longrunning.Operation.error] value with a [google.rpc.Status.code][google.rpc.Status.code] of 1,
corresponding to Code.CANCELLED.
Sample code:
$options = [
'apiEndpoint' => 'my-service-address',
'scopes' => ['my-service-scope'],
];
$operationsClient = new OperationsClient($options);
try {
$name = '';
$operationsClient->cancelOperation($name);
} finally {
if (isset($operationsClient)) {
$operationsClient->close();
}
}
deleteOperation(string $name, array $optionalArgs = [])
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.
Sample code:
$options = [
'apiEndpoint' => 'my-service-address',
'scopes' => ['my-service-scope'],
];
$operationsClient = new OperationsClient($options);
try {
$name = '';
$operationsClient->deleteOperation($name);
} finally {
if (isset($operationsClient)) {
$operationsClient->close();
}
}
