Examples of org.apache.accumulo.core.data.Key.compareTo()

org.apache.accumulo.core.data.Key.compareTo()
Compare elements of a key given by a {@link PartialKey}. For example, for {@link PartialKey#ROW_COLFAM}, compare just the row and column family. If the rows are not equal, return the result of the row comparison; otherwise, return the result of the column family comparison. @see #compareTo(Key)

        if (startKey.compareTo(getTopKey()) >= 0 && startKey.compareTo(iiter.peekPrevious().getKey()) <= 0) {
          // start key is within the unconsumed portion of the current block
          
          // this code intentionally does not use the index associated with a cached block
          // because if only forward seeks are being done, then there is no benefit to building
          // and index for the block... could consider using the index if it exist but not
