It extends a ComputationDeviceActor with a DynamicDeviceLifecycleBehavior.
It extends a ComputationDeviceActor with a DynamicDeviceLifecycleBehavior. In other words, the computation device has a (possibly dynamic) lifecycle that depends on the current execution scope (see ExecScope).
Defines a device lifecycle behavior that depends on the field {{execScope}.
Defines a device lifecycle behavior that depends on the field {{execScope}. The characteristic is that the behavior is dynamic, namely, can accomodate change to its execution scope. (See ExecScope)
A generic scheduler.
A generic scheduler. When it decides or someone decides its time to schedule (reception of a GoOn msg), it determines the next device to run ({{nextToRun: ()=>Option[ID]}}) and, if any, determines the destination mailbox ({{recipientForExecution: ID=>ActorRef}}) and sends to it a schedule tick (GoOn msg).
Behavior that should support the retrieval of missing class dependencies.
Behavior that should support the retrieval of missing class dependencies. - Missing classes are identified through a SystemMsgClassNotFound msg which is produced by the CustomSerializer when deserialization fails due to ClassNotFoundException, and replaces the original message - Then, requests for dependencies are carried out via MsgRequestClass messages - Finally, responses for dependency requests consist in MsgWithClass or MsgWithClasses messages
This behavior uses: - The CodeMobilityExtension to dynamically access the classloader for loading classes at runtime - The LoadClassBytes utility for getting the bytes of a class

Extends a ComputationDeviceActor with an ObservableActorBehavior.
Extends a ComputationDeviceActor with an ObservableActorBehavior. In other wards, it defines a computation device actors that is also observable, that is, can handle a set of observers and can notify them when certain events occur. In particular, observers are notified:
