Interface ObjectContext

All Superinterfaces:

Context, SharedObjectContext

All Known Subinterfaces:

WorkflowContext

All Known Implementing Classes:

FakeContext

@Deprecated(since="2.9",
            forRemoval=true)
public interface ObjectContext
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The Context-parameter programming model is superseded by the reflection-based API.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 an ObjectContext parameter, use Restate.state() (which supports both reads and writes) inside the handler. See the migration guide.

This interface can be used only within exclusive handlers of virtual objects. It extends Context adding access to the virtual object instance key-value state storage.

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