<div class="block">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 filterRowKey returns true, filterCell needs to be consistent with it.
filterCell can assume that filterRowKey has already been called for the row.
If your filter returns <code>ReturnCode.NEXT_ROW</code>, it should return
<code>ReturnCode.NEXT_ROW</code> until <a href="../../../../../../org/apache/hadoop/hbase/filter/Filter.html#reset--"><code>Filter.reset()</code></a> is called just in case the caller calls
for the next row.
