class CqlTransformFilter extends FilterBase
HBase filter for CQL predicates and transformations
The internal processing logic is kept in a delegate filter that will do either filtering, transforming, or both.

From the Filter javadocs:
From the Filter javadocs:
A filter can expect the following call sequence:
-
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. SeeReturnCode. -
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.
