Operation

public interface Operation

androidx.work.Operation

An object that provides information about the execution of an asynchronous command being performed by WorkManager. Operations are generally tied to enqueue or cancel commands; when you call one of those commands, they occur asynchronously. You can observe or await these commands by using the returned Operation.

Summary

Nested classes
`class`	`Operation.State` The lifecycle state of an `Operation`.

Public methods
`abstract ListenableFuture<Operation.State.SUCCESS>`	`getResult()` Gets a `ListenableFuture` for the terminal state of the `Operation`.
`abstract LiveData<Operation.State>`	`getState()` Gets a `LiveData` of the Operation `Operation.State`.

Public methods

getResult

public abstract ListenableFuture<Operation.State.SUCCESS> getResult ()

Gets a ListenableFuture for the terminal state of the Operation. This will only resolve with a Operation.State.SUCCESS. The Operation.State.FAILURE state will come through as a Throwable on the ListenableFuture. Operation.State.IN_PROGRESS will never be reported as it's not a terminal state.

Call Future.get() to block until the Operation reaches a terminal state.

Returns
`ListenableFuture<Operation.State.SUCCESS>`	A `ListenableFuture` with information about `Operation`'s `Operation.State.SUCCESS` state.

getState

public abstract LiveData<Operation.State> getState ()

Gets a LiveData of the Operation Operation.State.

Returns
`LiveData<Operation.State>`	A `LiveData` of the Operation `Operation.State`; you must use `LiveData.observe(LifecycleOwner, Observer)` to receive updates
