   Possible javadoc for this new method.
   
   ```java
     /**
      * Use this method to set a value when its expected that there is no 
current value.  In the event it is 
      * present, then the transaction will fail to commit. This method allows a 
read to be avoided in the case
      * where something is normally expected to be absent.
      */
      public void setIfAbsent(Bytes row, Column col, Value val);
