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)
