QCollatorSortKey:: QCollatorSortKey (const QCollatorSortKey & other )

构造副本为 other collator key.

QCollatorSortKey &QCollatorSortKey:: operator= ( QCollatorSortKey && other )

移动赋值 other to this collator key.

QCollatorSortKey &QCollatorSortKey:: operator= (const QCollatorSortKey & other )

赋值 other to this collator key.

QCollatorSortKey:: ~QCollatorSortKey ()

Destroys the collator key.

int QCollatorSortKey:: compare (const QCollatorSortKey & otherKey ) const

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 .

另请参阅 operator< ().

void QCollatorSortKey:: swap ( QCollatorSortKey & other )

Swaps this collator key with other .
