\p Options are:
- - \p opt::lock_type - lock type for node-level locking. Default \p is cds::lock::Spin. Note that <b>each</b> node
+ - \p opt::lock_type - lock type for node-level locking. Default \p is cds::sync::spin. Note that <b>each</b> node
of the list has member of type \p lock_type, therefore, heavy-weighted locking primitive is not
acceptable as candidate for \p lock_type.
- \p opt::compare - key compare functor. No default functor is provided.
If the option is not specified, the \p opt::less is used.
- \p opt::less - specifies binary predicate used for key compare. Default is \p std::less<T>.
+ - \p opt::equal_to - specifies binary functor for comparing keys for equality. No default is provided. If \p equal_to is
+ not specified, \p compare is used, if \p compare is not specified, \p less is used.
+ - \p opt::sort - specifies ordering policy. Default value is \p true.
- \p opt::back_off - back-off strategy used. If the option is not specified, \p cds::backoff::Default is used.
- \p opt::item_counter - the type of item counting feature. Default is disabled (\p atomicity::empty_item_counter).
To enable item counting use \p atomicity::item_counter.
