LROPoller Class

Poller for long running operations.

Inheritance

Generic

LROPoller

Constructor

LROPoller(client: Any, initial_response: Any, deserialization_callback: Callable[[Any], PollingReturnType_co], polling_method: PollingMethod[PollingReturnType_co])

Parameters

Name	Description
client Required	PipelineClient A pipeline service client
initial_response Required	PipelineResponse The initial call response
deserialization_callback Required	callable or <xref:msrest.serialization.Model> A callback that takes a Response and return a deserialized object. If a subclass of Model is given, this passes "deserialize" as callback.
polling_method Required	PollingMethod The polling strategy to adopt

Methods

add_done_callback	Add callback function to be run once the long running operation has completed - regardless of the status of the operation.
continuation_token	Return a continuation token that allows to restart the poller later.
done	Check status of the long running operation.
from_continuation_token
polling_method	Return the polling method associated to this poller.
remove_done_callback	Remove a callback from the long running operation.
result	Return the result of the long running operation, or the result available after the specified timeout.
status	Returns the current status string.
wait	Wait on the long running operation for a specified length of time. You can check if this call as ended with timeout with the "done()" method.

add_done_callback

Add callback function to be run once the long running operation has completed - regardless of the status of the operation.

add_done_callback(func: Callable) -> None

Parameters

Name	Description
func Required	callable Callback function that takes at least one argument, a completed LongRunningOperation.

continuation_token

Return a continuation token that allows to restart the poller later.

continuation_token() -> str

Returns

Type	Description
str	An opaque continuation token

done

Check status of the long running operation.

done() -> bool

Returns

Type	Description
bool	'True' if the process has completed, else 'False'.

from_continuation_token

from_continuation_token(polling_method: PollingMethod[PollingReturnType_co], continuation_token: str, **kwargs: Any) -> LROPoller[PollingReturnType_co]

Parameters

Name	Description
polling_method Required
continuation_token Required

polling_method

Return the polling method associated to this poller.

polling_method() -> PollingMethod[PollingReturnType_co]

Returns

Type	Description
PollingMethod	The polling method

remove_done_callback

Remove a callback from the long running operation.

remove_done_callback(func: Callable) -> None

Parameters

Name	Description
func Required	callable The function to be removed from the callbacks.

Exceptions

Type	Description
ValueError	if the long running operation has already completed.

result

Return the result of the long running operation, or the result available after the specified timeout.

result(timeout: float | None = None) -> PollingReturnType_co

Parameters

Name	Description
timeout	float Period of time to wait before getting back control. default value: None

Returns

Type	Description
any, None	The deserialized resource of the long running operation, if one is available.

Exceptions

Type	Description
HttpResponseError	Server problem with the query.

status

Returns the current status string.

status() -> str

Returns

Type	Description
str	The current status string

wait

Wait on the long running operation for a specified length of time. You can check if this call as ended with timeout with the "done()" method.

wait(timeout: float | None = None) -> None

Parameters

Name	Description
timeout Required	float Period of time to wait for the long running operation to complete (in seconds).
