Interface StatusCode

All Known Implementing Classes:

CanonicalExitCode

public interface StatusCode

Status code enumerations. Enumerations that implement this interface can be used as status codes, which are arguments for the method Options#exit(Enum).

!ATTENTION! Enum.ordinal() is used as the status code, when the method System.exit(int) is called. Meaning, the first enumeration constant should necessarily mean successful program execution, since its ordinal will be zero.
