用enum代替if.这个设计大家怎么看

public class HandleSomething  {

    private static Manager manager;

    private static Logger subLogger = LoggerFactory.getLogger(HandleSomething.class);

    protected void work(int entryType, long userId, Context context)  {
          int type = Flow.fromEntryType(entryType).handle(userId);
          context.put("type",type);                            		
    }

    private static enum Flow{
        VIP_ENTRY_FLOW (1) {// 特殊页面进入
            @Override
            int handle(long userId) {
               /*这里的逻辑用到manager和subLogger*/
        },

        INDEX_ENTRY_FLOW (2) {// 首页进入
            @Override
            int handle(long userId) {
               /*这里的逻辑用到manager和subLogger*/
        },
        OTHERS_ENTRY_FLOW (3){ // 其他页面进来	
            @Override
            int handle(long userId) {
              /*这里的逻辑用到manager和subLogger*/
            }
        };
        private final int tag;

        private Flow(Integer tag){
          this.tag=tag;
        }  
        public abstract int handle(long userId);
    }
}
