org.apache.hadoop.hbase.filter.Filter.filterKeyValue()
A way to filter based on the column family, column qualifier and/or the column value. Return code is described below. This allows filters to filter only certain number of columns, then terminate without matching ever column. If your filter returns ReturnCode.NEXT_ROW, it should return ReturnCode.NEXT_ROW until {@link #reset()} is calledjust in case the caller calls for the next row. @param v the KeyValue in question @return code as described below @see Filter.ReturnCode

    long now = tx.getVisibilityUpperBound();
    Filter filter = createFilter(tx, ttls);
    assertEquals(Filter.ReturnCode.INCLUDE_AND_NEXT_COL,
                 filter.filterKeyValue(newKeyValue("row1", FAM, "val1", now)));
    assertEquals(Filter.ReturnCode.INCLUDE_AND_NEXT_COL,
                 filter.filterKeyValue(newKeyValue("row1", FAM, "val1", now - 1 * TxConstants.MAX_TX_PER_MS)));
    assertEquals(Filter.ReturnCode.NEXT_COL,
                 filter.filterKeyValue(newKeyValue("row1", FAM, "val1", now - 11 * TxConstants.MAX_TX_PER_MS)));
