| | | | | | | | | | | | | | | | | | possible If QList data-layout-compatible with QVector and a C array, implement count() via std::count() and contains() via std::find() and use const_pointer instead of const_iterator as the iterators. This essentially makes the QVector and QList implementations identical to each other, at least for important cases such as QString. To switch between the different implementations, use tag dispatching instead of the previously used technique "use 'if' as if it were 'static if'", which imposes accidental requirements on the element types (something that esp. QVector is plagued with). Change-Id: I6caf74442a22059676b5bf115a6089768f3a0952 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* QList: prepare for tag dispatching based on memory layoutMarc Mutz2015-02-171-0/+19
| | | | | | | | | | | | | Add one tag class for each of QList's three different memory layouts to QListData, and inherit QList<T>::MemoryLayout from exactly one of them. To simplify overloading, added tag classes that express the negation of the two extreme poles of memory layout (C-compatible and heap), too. The "missing" one could be added when needed, too.

* QTimeZone: don't use QSet, use sorted QListMarc Mutz2015-02-177-95/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | QSet, as a node-based container, requires one memory allocation per element inserted. QList, as a contiguous-memory container (at least in the case of a QByteArray payload), requires one memory allocation per container. The higher lookup speed might still speak for using QSet, but there are only two uses of the sets: 1. Checking for existence (or lack thereof) of timezone names. For this, first generating a container full of data just to check for existence of one item of data is extremely wasteful. The QTZPrivate API should be extended to allow said lookup to be performed on the native data store instead. That leaves 2. Returning a sorted(!) list(!) from the public QTimeZone API. There is no reason why, during the construction of those sorted lists, the data should be held in a set. Instead, the well-known technique of first cramming everything into a result container, which is subsequently sorted and has its duplicates removed, can be used here. Saves more than 8K of text size on AMD64 stripped release builds. Change-Id: I71c2298e94e02d55b0c9fb6f7ebeaed79a1fe2db Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
