public class Retry
extends EventCompoundImpl
implements Compound

Retry is a modified compound which differs in that its single sub-component is created and should it terminate abnormally, is recreated. This is repeated a number of times or until the sub-component suceeds. A Retry combinator creates no subcomponents until it's sfStart phase at which point all the subcomponent is created in the normal way. The Retry combinator waits for its sub-component to terminate normally at which point it too terminates normally. If an error occurs at any point, or a sub-component is retried unless a limit is reached in which case it too terminates abnormall.

The file retry.sf contains the SmartFrog configuration file for the base Retry combinator. This file conatins the details of the attributes which may be passed to Retry.

Constructor Detail

Retry

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

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

sfDeploy

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

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 any error while deploying the component

sfStart

public void sfStart()
             throws SmartFrogException,
                    java.rmi.RemoteException
Starts the component and starts subcomponents. Overrides CompoundImpl.sfStart.

Specified by:
sfStart in interface Prim
Overrides:
sfStart in class CompoundImpl
Throws:
java.rmi.RemoteException - The required remote exception.
java.rmi.RemoteException - In case of network/rmi error
SmartFrogException - failed to start compound

sfTerminatedWith

public void sfTerminatedWith(TerminationRecord status,
                             Prim comp)
Terminates the component. This is invoked by sub-components on termination. If normal termination, Retry behaviour is to terminate normally. If an abnormal termination - retry unless some limit is reached, in which case terminate abnormally.

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