public class Repeat
extends EventCompoundImpl
implements Compound

Repeat is a modified compound which differs in that its single sub-component is created and should it terminate normally, is recreated. This is repeated a number of times or indefinitely unless the sub-component terminates abnormally . A Repeat combinator creates no subcomponents until it's sfStart phase at which point the subcomponent is created in the normal way. The Repeat combinator terminates normally if the sub-component has terminated normally a given number of times, and abnormally whenever the component terminates abnormally. The file repeat.sf contains the SmartFrog configuration file for the base Repeat combinator. This file conatins the details of the attributes which may be passed to Repeat.

Constructor Detail

Repeat

public Repeat()
       throws java.rmi.RemoteException
Constructs Repeat.

Throws:
java.rmi.RemoteException - In case of network or RMI error.
Method Detail

sfDeploy

public void sfDeploy()
              throws SmartFrogException,
                     java.rmi.RemoteException
Reads the basic configuration of the component and deploys the component.

Specified by:
sfDeploy in interface Prim
Overrides:
sfDeploy in class EventCompoundImpl
Throws:
java.rmi.RemoteException - In case of network/rmi error
SmartFrogException - In case of SmartFrog system deployment error

sfStart

public void sfStart()
             throws SmartFrogException,
                    java.rmi.RemoteException
Starts the component and the deploys and manages the subcomponents.

Specified by:
sfStart in interface Prim
Overrides:
sfStart in class CompoundImpl
Throws:
SmartFrogException - In case of SmartFrog system error
java.rmi.RemoteException - In case of network/rmi error

sfTerminatedWith

public void sfTerminatedWith(TerminationRecord status,
                             Prim comp)
Terminates the component. It is invoked by sub-component on termination. If abnormal termination, Repeat behaviour is to terminate abnormally. On normal termination - repeat unless some count is reached, in which case terminate normally.

Specified by:
sfTerminatedWith in interface Prim
Overrides:
sfTerminatedWith in class CompoundImpl
Parameters:
status - termination status of sender
comp - sender of termination
