All Implemented Interfaces:

ExitCodeMapper

public class SimpleJvmExitCodeMapper
extends java.lang.Object
implements ExitCodeMapper

An implementation of ExitCodeMapper that can be configured through a map from batch exit codes (String) to integer results. Some default entries are set up to recognise common cases. Any that are injected are added to these.
