Poller for long running operations.

Inheritance

Generic

LROPoller

Constructor

LROPoller(client: Any, initial_response: Any, deserialization_callback: Callable, polling_method: azure.core.polling._poller.PollingMethod[PollingReturnType])

Parameters

client

PipelineClient

Required

A pipeline service client

initial_response

PipelineResponse

Required

The initial call response

deserialization_callback

callable or Model

Required

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

PollingMethod

Required

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

func

callable

continuation_token

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

continuation_token() -> str

Returns

Return type

str

done

Check status of the long running operation.

done() -> bool

Returns

'True' if the process has completed, else 'False'.

Return type

bool

from_continuation_token

from_continuation_token(polling_method: azure.core.polling._poller.PollingMethod[PollingReturnType], continuation_token: str, **kwargs: Any) -> azure.core.polling._poller.LROPoller[PollingReturnType]

Parameters

polling_method

Required

continuation_token

Required

polling_method

Return the polling method associated to this poller.

polling_method() -> azure.core.polling._poller.PollingMethod[PollingReturnType]

remove_done_callback

Remove a callback from the long running operation.

remove_done_callback(func: Callable) -> None

Parameters

func

callable

Required

The function to be removed from the callbacks.

Exceptions

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

result(timeout: Optional[int] = None) -> PollingReturnType

Parameters

status

Returns the current status string.

status() -> str

Returns
