list::splice
移除引數清單中的項目並將它們插入至目標清單。
void splice(
iterator _Where,
list<Type, Allocator>& _Right
);
void splice(
iterator _Where,
list<Type, Allocator>& _Right,
iterator _First
);
void splice(
iterator _Where,
list<Type, Allocator>& _Right,
iterator _First,
iterator _Last
);
參數
_Where
在目前的引數清單項目將插入的目標清單的位置。_Right
要插入目標清單的引數清單。_First
在從引數清單中插入的範圍中第一個項目。_Last
在從引數清單中插入的範圍的第一個項目。
備註
第 10% 成員函式在項目前面插入在引數清單中的所有項目 _Where 位於目標清單。 從引數清單中移除所有項目。
,要在目標清單的項目會指向由 _Where之前,第二 + 成成員函式移除項目指向在引數清單中 _First 並將其插入。
第三 + 成成員函式插入從引數清單中所指定的 [_First, _Last) 範圍,在目標清單的項目會指向由 _Where之前。 從引數清單同時移除插入的範圍。
在所有情況下,指向在要連接之項目的 Iterator 或參考就會變成無效。
