Enum Class ProgramStatus

java.lang.Object
java.lang.Enum<ProgramStatus>
mars.venus.execute.ProgramStatus
All Implemented Interfaces:
Serializable, Comparable<ProgramStatus>, Constable
public enum ProgramStatus extends Enum<ProgramStatus>
Enumeration to indicate the status of the current program (which may involve more than one file). These status values were originally part of FileStatus, but were split off to eliminate unnecessary global state in the class.
