Andrew Purtell updated HBASE-1005:
----------------------------------

    Attachment: 1005.patch

One way to do it is attached. String and regex matching are reimplemented as classes that implement WritableByteArrayComparable that can be used in conjunction with ColumValueFilter. These comparators are useful only if tested with EQUAL or NOT_EQUAL.
