Sylvain Lebresne updated CASSANDRA-2355:
----------------------------------------
Description:
Being able to provide arguments to a comparator, to parametrize its behavior,
can be useful.
For example, a generic ReverseComparator is trivial to write, but without the
ability to provide arguments at the comparator constriction, it cannot be used.
CASSANDRA-2231 provides another use case for this.
This ticket proposes to introduce a parser for comparator definition that
supports optional parameters and to introduce a generic ReverseType as a simple
example of this.
Fix Version/s: 0.7.5
Summary: Allow parameters for comparator (was: Have an easy way to
define the reverse comparator of any comparator)
