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

sfTerminatedWith

public void sfTerminatedWith(TerminationRecord status,
                             Prim comp)

Specified by:

sfTerminatedWith in interface Prim

Overrides:

sfTerminatedWith in class CompoundImpl

Parameters:

status - termination status of sender

comp - sender of termination
