C# Class Summer.Batch.Core.Step.Tasklet.SystemCommandTasklet

ITaskletthat executes a system command. The system command is executed asynchronously using injected ITaskExecutor - timeout value is required to be set, so that the batch job does not hang forever if the external process hangs. Tasklet periodically checks for termination status (i.e. Command finished its execution or timeout expired or job was interrupted). The check interval is given by TerminationCheckInterval. When job interrupt is detected tasklet's execution is terminated immediately by throwing JobInterruptedException. NOTE : InterruptOnCancel is not being supported for now.
