Detailed Description

template<typename... Options>
struct cds::intrusive::optimistic_queue::make_traits< Options >

Metafunction converting option list to optimistic_queue::traits.

Supported Options are:

• opt::hook - hook used. Possible hooks are: optimistic_queue::base_hook, optimistic_queue::member_hook, optimistic_queue::traits_hook. If the option is not specified, optimistic_queue::base_hook<> is used.
• opt::back_off - back-off strategy used, default is cds::backoff::empty.
• opt::disposer - the functor used for dispose removed items. Default is opt::v::empty_disposer. This option is used when dequeuing.
• opt::link_checker - the type of node's link fields checking. Default is opt::debug_check_link
• opt::item_counter - the type of item counting feature. Default is cds::atomicity::empty_item_counter (item counting disabled) To enable item counting use cds::atomicity::item_counter
• opt::stat - the type to gather internal statistics. Possible statistics types are: optimistic_queue::stat, optimistic_queue::empty_stat, user-provided class that supports optimistic_queue::stat interface. Default is optimistic_queue::empty_stat (internal statistics disabled).
• opt::padding - padding for internal critical atomic data. Default is opt::cache_line_padding
• opt::memory_model - C++ memory ordering model. Can be opt::v::relaxed_ordering (relaxed memory model, the default) or opt::v::sequential_consistent (sequentially consisnent memory model).

Example: declare OptimisticQueue with item counting and internal statistics

typedef cds::intrusive::OptimisticQueue< cds::gc::HP, Foo,
    typename cds::intrusive::optimistic_queue::make_traits<
        cds::intrusive::opt:hook< cds::intrusive::optimistic_queue::base_hook< cds::opt::gc<cds:gc::HP> >>,
        cds::opt::item_counte< cds::atomicity::item_counter >,
        cds::opt::stat< cds::intrusive::optimistic_queue::stat<> >
    >::type
> myQueue;
