Member Function Documentation
QCollatorSortKey::QCollatorSortKey(const QCollatorSortKey &other)
Constructs a copy of the other collator key.
QCollatorSortKey &QCollatorSortKey::operator=(QCollatorSortKey &&other)
Move-assigns other to this collator key.
QCollatorSortKey &QCollatorSortKey::operator=(const QCollatorSortKey &other)
Assigns other to this collator key.
QCollatorSortKey::~QCollatorSortKey()
Destroys the collator key.
int QCollatorSortKey::compare(const QCollatorSortKey &otherKey) const
Compares this key to otherKey.
Returns a negative value if the key is less than otherKey, 0 if the key is equal to otherKey or a positive value if the key is greater than otherKey.
See also operator<().
void QCollatorSortKey::swap(QCollatorSortKey &other)
Swaps this collator key with other.

bool operator<(const QCollatorSortKey &lhs, const QCollatorSortKey &rhs)
According to the QCollator that created the keys, returns true if lhs should be sorted before rhs; otherwise returns false.
