Class RunOperation

java.lang.Object

schema.RunOperation

abstract class RunOperation
extends Object

Utility class to run a KVStore operation and handle FaultExceptions according to this application's policies. The doOperation method is abstract and must be implemented by callers. doOperation is called by the run() method of this class.

This class is a placeholder for implementing application-specific exception handling policies. This implementation simply prints the exception details to System.err. In addition to performing other actions when an exception occurs, applications may wish to extend this mechanism to perform retries under certain conditions.

Note that OperationExecutionException is not handled by this class because it is a contingency exception that is expected to be handled by the operation itself (the doOperation method).
