Description copied from class: AbstractStrategyHolder

SSTables are grouped by their repaired and pending repair status. This method determines if this holder holds the sstable for the given repaired/grouped statuses. Holders should be mutually exclusive in the groups they deal with. IOW, if one holder returns true for a given isRepaired/isPendingRepair combo, none of the others should.
