Interface SharedWorkflowContext

All Superinterfaces:

Context, SharedObjectContext

All Known Subinterfaces:

WorkflowContext

All Known Implementing Classes:

FakeContext

@Deprecated(since="2.9",
            forRemoval=true)
public interface SharedWorkflowContext
extends SharedObjectContext

Deprecated, for removal: This API element is subject to removal in a future version.

The Context-parameter programming model is superseded by the reflection-based API. Rather than accepting a SharedWorkflowContext parameter, use Restate.promise(...), Restate.promiseHandle(...) and Restate.state() inside the handler. See the migration guide.

This interface can be used only within shared handlers of workflow. It extends Context adding access to the workflow instance key-value state storage and to the DurablePromise API.

NOTE: This interface MUST NOT be accessed concurrently since it can lead to different orderings of user actions, corrupting the execution of the invocation.

Method Details

promise

<T> DurablePromise<T> promise(DurablePromiseKey<T> key)

Deprecated, for removal: This API element is subject to removal in a future version.

Create a DurablePromise for the given key.

You can use this feature to implement interaction between different workflow handlers, e.g. to send a signal from a shared handler to the workflow handler.

Returns:

the DurablePromise.
