初始化器
init(rebasing:)
在與給定緩衝區切片相同的內存上創建緩衝區。
聲明
init(rebasing slice: Slice<UnsafeMutableBufferPointer<Element>>)
參數
slice
要變基的緩衝區切片。
詳述
新緩衝區表示與 slice
相同的內存區域,但從零開始索引,而不是與原始緩衝區共享索引。例如:
let buffer = returnsABuffer()
let n = 5
let slice = buffer[n...]
let rebased = UnsafeMutableBufferPointer(rebasing: slice)
將 slice
重新設置為 rebased
緩衝區後,以下情況為真:
-
rebased.startIndex == 0
-
rebased[0] == slice[n]
-
rebased[0] == buffer[n]
-
rebased.count == slice.count
