RoundRobinProtocol (Tweety (Agents Library) 1.17 API)

All Implemented Interfaces:

Protocol
```
public class RoundRobinProtocol
extends RigidProtocol
```
This class models a round robin protocol for multi-agent systems. This protocol assumes some order of the agents and asks each agent for some action which is directly executed in the environment. This process is repeated for all agents. The protocol can optionally be defined as rigid, i.e. if at any time an agent performs a "NO_OPERATION" he cannot perform any other action thereafter.
This protocol terminates when there has been no actions for a full round or (if the protocol is defined to be rigid) after all agents performed one NO_OPERATION.

```
public RoundRobinProtocol(MultiAgentSystem<? extends Agent> multiAgentSystem)
```
    Creates a new (non-rigid) round robin protocol for the given multi-agent system.
    
    Parameters:
    
    multiAgentSystem - a multi-agent system.
  - RoundRobinProtocol
```
public RoundRobinProtocol(MultiAgentSystem<? extends Agent> multiAgentSystem,
                          boolean isRigid)
```
    Creates a new (non-rigid) round robin protocol for the given multi-agent system.
    
    Parameters:
    
    multiAgentSystem - a multi-agent system.

- Method Detail
  - hasTerminated
```
protected boolean hasTerminated()
```
    Description copied from class: AbstractProtocol
    
    This method determines if this protocol has terminated, i.e. whether no further actions are possible.
    
    Overrides:
    
    hasTerminated in class RigidProtocol
    
    Returns:
    
    "true" if this protocol system has terminated.
  - doStep
```
protected Set<ActionEvent> doStep()
                           throws ProtocolTerminatedException
```
    Description copied from class: AbstractProtocol
    
    Executes one step of the protocol.
    
    Specified by:
    
    doStep in class AbstractProtocol
    
    Returns:
    
    the set of events that occurred.
    
    Throws:
    
    ProtocolTerminatedException - if the protocol already terminated
