Method Detail

create

public abstract T create(CFMetaData metadata,
       boolean insertReversed)

Returns a (initially empty) column map whose columns are sorted according to the provided comparator. The insertReversed flag is an hint on how we expect insertion to be perfomed, either in sorted or reverse sorted order. This is used by ArrayBackedSortedColumns to allow optimizing for both forward and reversed slices. This does not matter for ThreadSafeSortedColumns. Note that this is only an hint on how we expect to do insertion, this does not change the map sorting.
