在学习cache过程中，看到枚举类来指定cache或cacheManager的状态，记录下来

public final class More ...Status implements Serializable {
         public static final Status STATUS_UNINITIALISED = new Status(0, "STATUS_UNINITIALISED");
    
         public static final Status STATUS_ALIVE = new Status(1, "STATUS_ALIVE");
    
         public static final Status STATUS_SHUTDOWN = new Status(2, "STATUS_SHUTDOWN");
    
         private static final long serialVersionUID = 2732730630423367732L;
     
         private static final Status[] STATUSES = {STATUS_UNINITIALISED, STATUS_ALIVE, STATUS_SHUTDOWN};
     
         private final String name;
         private final int intValue;
     
         private Status(int intValue, String name) {
             this.intValue = intValue;
             this.name = name;
     
         }
    
         public static Status More ...convertIntToStatus(int statusAsInt) throws IllegalArgumentException {
             if ((statusAsInt < STATUS_UNINITIALISED.intValue) || (statusAsInt > STATUS_SHUTDOWN.intValue)) {
                 throw new IllegalArgumentException("int value of statuses must be between 1 and three");
             }
             return STATUSES[statusAsInt];
         }
    
         public String More ...toString() {
             return name;
         }
    
         public int intValue() {
            return intValue;
        }
    
        public boolean More ...equals(Object object) {
            if (!(object instanceof Status)) {
                return false;
            }
            return ((Status) object).intValue == intValue;
        }
    
        public int More ...hashCode() {
            return intValue;
        }
