Not, strictly speaking, a part of the collections framework, this feature was added to the Java platform at the same time as the collections framework and relies on some of the same infrastructure. Collection Interfaces The collection interfaces are divided into two groups. The most basic ...
Note: In a way, it works in an opposite way from a “normal” Java type assignment. For example, Employee emp = new Manager(); makes emp object an instance of Manager. But in the case of generics: ArrayList[Manager] managementTeam = new ArrayList[](); ...
The main design goal was to produce an API that was small in size and, more importantly, in "conceptual weight." It was critical that the new functionality not seem too different to current Java programmers; it had to augment current facilities, rather than replace them. At the same time,...
若要间接处理它,请使用语言构造(如 using(在 C# 中)或 Using(在 Visual Basic 中)。 有关详细信息,请参阅 IDisposable 接口主题中的“使用实现 IDisposable 的对象”部分。 另请注意,Dispose() 方法不是线程安全的。 BlockingCollection<T> 的所有其他公共和受保护成员都是线程安全的,可以从多个线程并发使用。
