SignalApi (scheduling 14.1.0-SNAPSHOT API)

All Superinterfaces:

All Known Implementing Classes:

SignalApiImpl

@PublicAPI
public interface SignalApi
extends Serializable
```
SignalApi uses the synchronization API store to provide a persistent key/value channel for job signals. SignalApi uses a single system channel to store all signals needed by jobs. The signal channel contains an entry per job. The key of each entry is the job id, whereas the value of the entry is the set of signals used by the considered job. The SignalApi service is automatically started with the ProActive Server.
