==过滤器执行流程==

• reset() : reset the filter state before filtering a new row.
• filterAllRemaining(): true means row scan is over; false means keep going.
• filterRowKey(byte[],int,int): true means drop this row; false means include.
• filterKeyValue(Cell): decides whether to include or exclude this KeyValue. See Filter.ReturnCode.
• transform(KeyValue): if the KeyValue is included, let the filter transform the KeyValue.
• filterRowCells(List): allows direct modification of the final list to be submitted
• filterRow(): last chance to drop entire row based on the sequence of filter calls. Eg: filter a row if it doesn\'t contain a specified column.
