Enhance checkAndPut and checkAndDelete with comparators
Review Request #1483 - Created Jan. 23, 2011 and updated
Enhance checkAndPut and checkAndDelete with comparators from o.a.h.h.filter. Rather than support only an equality test against a binary string, test for any comparison operator result: LESS, LESS_OR_EQUAL, EQUAL, NOT_EQUAL, GREATER_OR_EQUAL, GREATER, and NO_OP; and compare using any of the comparators that extend WritableByteArrayComparable: Binary, BinaryPrefix, RegexString, Substring.
All existing unit tests pass. Converted unit tests pass, but test using CompareOp.EQUALS only. Could use more unit tests covering all new functionality.
