process

public Set<Result> process(Context context)
                    throws org.apache.commons.configuration.ConfigurationException

This method processes the input Context and forwards the results on to the successor. This implementation of the method simply checks if there are any successors and passes the context. if no successor is registered for the command then it merely returns the results from the context. The method also fires a BasicChainEvent before sending the control to the successor command with an END Type. This behavior allows the subclasses to concentrate in processing the input while the rest of the package releases all the features of event firing and handling. Events can be fired from within subclasses but it is better not to fire END events as this is handled here. START events though, must be fired in the subclasses if they are needed.
