duplicate code in NioProcessor.java

[houzhanbin]

hi,developers,
  I find an duplicate code in NioProcessor.java, I think they do the 
same thing.

 (1)
  protected boolean isInterestedInRead(NioSession session) {
       SelectionKey key = session.getSelectionKey();
       return key.isValid() && (key.interestOps() & 
SelectionKey.OP_READ) != 0;
   }
 (2)
   protected boolean isReadable(NioSession session) {
       SelectionKey key = session.getSelectionKey();
       return key.isValid() && key.isReadable();
   }
  the code comes from mina-2.0.0-M4
thanks for your reply..
