ReadonlynameThe name for this actor.
Cluster the given operations by equal source annotations.
An array of operations to cluster.

ProtectedlogOptionaldata: () => anyProtectedlogOptionaldata: () => anyProtectedlogOptionaldata: () => anyProtectedlogOptionaldata: () => anyProtectedlogOptionaldata: () => anyProtectedlogOptionaldata: () => anyIf the given source accepts the grouped operation, annotate the grouped operation with the source, and remove the source annotation from the seperate input operations. Otherwise, return the grouped operation unchanged.

The action to run.
A promise that resolves to the run result.
Run the given action on this actor AND invokes the Bus#onRun method.
The action to run.
A promise that resolves to the run result.
Check if this actor can run the given action, without actually running it.
