QcIdList Class

template <typename Id, typename T> class QcIdList

A read-only view of the definitions (of the type T) of a content registry list, indexed by their strong id type Id instead of an integer (decision E-952). More...

Detailed Description

Id has an explicit constructor from int and index(). The view holds a pointer to the list: it is valid as long as the registry it came from. Iterating it yields the definitions in registration order; ids() yields their ids.

Member Function Documentation

`[explicit]` QcIdList::QcIdList(const QList<T> &items)

Constructs a view of items.

`[delete]` QcIdList::QcIdList(const QList<T> &&)

A view of a temporary list would dangle.

const T &QcIdList::at(Id id) const

Returns the definition of id; id must be in the list (contains()).

typename QList<T>::const_iterator QcIdList::begin() const

Returns an iterator to the first definition.

bool QcIdList::contains(Id id) const

Returns whether id names a definition of the list.

typename QList<T>::const_iterator QcIdList::end() const

Returns the iterator past the last definition.

Id QcIdList::idOf(typename QList<T>::const_iterator it) const

Returns the id of the definition it points to (an iterator of this list).

auto QcIdList::ids() const

Returns the ids of all definitions in registration order.

bool QcIdList::isEmpty() const

Returns whether the list holds no definition.

const QList<T> &QcIdList::list() const

Returns the underlying list, for code that hands it on unchanged.

qsizetype QcIdList::size() const

Returns the number of definitions.

const T &QcIdList::operator[](Id id) const
