BitArray类用于以紧凑的方式表示"位的集合"(sets of bits). 虽然我们能把位的集合存储在常规数组内, 但是如果采用专门为位的集合设计的数据结构就能创建更加有效率的程序. 本章将会介绍如何使用这种数据结构, 并且将讨论一些利用位的集合所解决的问题. 此外, 本章节还包含二
var isEmpty: Bool A Boolean value indicating whether the collection is empty. var count: Int The number of elements in the array. var capacity: Int The total number of elements that the array can contain without allocating new storage. Accessing Elements subscript(Int) -> Element Accesses the...

Note that the previous CComSafeArray<BSTR>::SetAt method call performs a deep copy of the input BSTR into the safe array. In fact, the SetAt method has an additional BOOL bCopy third parameter, which is defaulted to TRUE. This bCopy flag parameter isn’t important for scalar t...
