iterator QLinkedList:: find ( iterator from , const T & t )

If you need random access to a data structure then QList , QVector , QMap ，或 QHash , are all better choices than QLinkedList .

例如，若有代码像

QLinkedList::iterator i = list->find(from, value);
					

可以把它重写成

QLinkedList::iterator i = from;
while (i != list->end() && *i != value)
    ++i;
					

iterator QLinkedList:: find (const T & t )

If you need random access to a data structure then QList , QVector , QMap ，或 QHash , are all better choices than QLinkedList .

例如，若有代码像

QLinkedList::iterator i = list->find(value);
					

可以把它重写成

QLinkedList::iterator i = list->begin();
while (i != list->end() && *i != value)
    ++i;
					

const_iterator QLinkedList:: find ( const_iterator from , const T & t ) const

If you need random access to a data structure then QList , QVector , QMap ，或 QHash , are all better choices than QLinkedList .

例如，若有代码像

QLinkedList::const_iterator i = list->find(from, value);
					

可以把它重写成

QLinkedList::const_iterator i = from;
while (i != list->end() && *i != value)
    ++i;
					

const_iterator QLinkedList:: find (const T & t ) const

If you need random access to a data structure then QList , QVector , QMap ，或 QHash , are all better choices than QLinkedList .

例如，若有代码像

QLinkedList::const_iterator i = list->find(value);
					

可以把它重写成

QLinkedList::const_iterator i = list->begin();
while (i != list->end() && *i != value)
    ++i;
					

int QLinkedList:: findIndex (const T & t ) const

If you need indexes then QList or QVector are better choices than QLinkedList .

例如，若有代码像

int index = list->findIndex(value);
					

可以把它重写成

int index = 0;
bool found = false;
for (const_iterator i = list->begin(); i != list->end(); ++i; ++index)
    if (*i == value) {
        found = true;
        break;
    }
if (!found)
    index = -1;
					

iterator QLinkedList:: remove ( iterator pos )

使用 erase () 代替。
