The QCollatorSortKey class is always created by QCollator::sortKey() and is used for fast strings collation, for example when collating many strings.
See also QCollator, QCollator::sortKey(), and compare().
Constructs a copy of the other collator key.
[constexpr noexcept, since 6.8] QCollatorSortKey::QCollatorSortKey(QCollatorSortKey &&other)Move-constructs a new QCollatorSortKey from other.
Note: The moved-from object other is placed in a partially-formed state, in which the only valid operations are destruction and assignment of a new value.
This function was introduced in Qt 6.8.
[noexcept] QCollatorSortKey::~QCollatorSortKey()Destroys the collator key.
Compares this key to otherKey, which must have been created by the same QCollator's sortKey() as this key. The comparison is performed in accordance with that QCollator's sort order.
Returns a negative value if this key sorts before otherKey, 0 if the two keys are equal or a positive value if this key sorts after otherKey.
See also operator<().
[noexcept] void QCollatorSortKey::swap(QCollatorSortKey &other)Swaps this collator key with other. This operation is very fast and never fails.
[noexcept] QCollatorSortKey
&QCollatorSortKey::operator=(QCollatorSortKey &&other)Move-assigns other to this QCollatorSortKey instance.
Note: The moved-from object other is placed in a partially-formed state, in which the only valid operations are destruction and assignment of a new value.
Assigns other to this collator key.
Both keys must have been created by the same QCollator's sortKey(). Returns true if lhs should be sorted before rhs,
according to the QCollator that created them; otherwise returns false.
See also QCollatorSortKey::compare().
