구문
‘선언
Public Overridable Sub RemoveRange ( _
index As Integer, _
count As Integer _
)
‘사용 방법
Dim instance As ArrayList
Dim index As Integer
Dim count As Integer
instance.RemoveRange(index, count)
public virtual void RemoveRange (
int index,
int count
)
public:
virtual void RemoveRange (
int index,
int count
)
public void RemoveRange (
int index,
int count
)
public function RemoveRange (
index : int,
count : int
)
매개 변수
- index
제거할 요소의 범위에 대한 인덱스(0부터 시작)입니다.
- count
제거할 요소의 수입니다.
예외
예외 형식 | 조건 |
---|---|
index가 0보다 작은 경우 - 또는 - count가 0보다 작은 경우 |
|
index 및 count가 ArrayList에 있는 요소의 올바른 범위를 나타내지 않는 경우 |
|
ArrayList가 읽기 전용인 경우 - 또는 - ArrayList의 크기가 고정되어 있는 경우 |
설명
목록과 같은 연속 요소 컬렉션에서는 제거된 요소의 다음 요소가 앞으로 이동하여 빈 지점을 채웁니다. 컬렉션이 인덱싱되면 이동되는 요소의 인덱스도 업데이트됩니다. 이 동작은 개념적으로 요소가 해시 테이블과 같은 버킷으로 그룹화되는 컬렉션에는 적용되지 않습니다.
이 메서드는 O(n) 연산이며, 여기서 n은 Count입니다.
예제
다음 코드 예제에서는 ArrayList에서 요소를 제거하는 방법을 보여 줍니다.
