It would be nice if thread safety were a binary attribute of a class, and you could just document whether the class is thread-safe or not. 如果线程安全性是类的一个二元属性就好了,您只需要记录类是线程安全还是线程不安全的。 www-128.ibm.com 2. At the heart of any reasonable definition of...
/* thread-unsafe function */intincrement_counter(){staticint counter=0;counter++;returncounter;} 为使该函数线程安全,静态变量 counter 需要被静态锁保护,如下例(伪代码)所示: 代码语言:javascript 复制 /* pseudo-code threadsafe function */intincrement_counter();{staticint counter=0;staticlock_type cou...

thread-safe用途 final关键字 上面介绍了final的常用用途,一句话概括就是“不可修改引用地址”,由于这个特性,使得final在修饰属性变量时可以达到一定程度的thread-safe。 假设我们有如下类: publicclassMultiReadResource{publicfinalintid;publicfinalListlist;publicMultiReadResource(intid,Listlist){this.id=id;this.li...
Static methods aren't inherently thread-safe. They're treated no differently by the CLR than instance methods. The difference is that one should generally try to make them thread-safe. (I can't think of any .NET BCL static methods which aren't thread-safe.) Instance methods are often not...
I know that it's in the C++11 standard and that current GCC version behave this way, but does VC2010 currently guarantees thread-safety of a local static variable initialization? i.e.: Is this thread-safe with VC2010? static S& getInstance() { static S instance; return instance; } ....
2.房产本身的init是thread-safe吗? 或者我们需要用某种实例getter(Java-style来包装它吗 extension A { static var newInstance -> A { return A() } } class B { public var a: A = A.newInstance } (Java的基本原理是:在这种情况下,指针在创建实例之前不会返回,而在直接初始化的情况下,指针是在初始...
I'm not quite sure how you want to express this in this documentation, but C# static class constructors are thread-safe, and executed under a lock that is specific to the exact specific type of the class. (This is important for generics, i.e. the List static class constructor executes ...
Are static classes thread safe? Are there any (simple) methods/libraries to recognize similar pictures using C# code? Are there any BIG commercial apps using .NET framework and C# Array and switch Array of Threads Array of Unknown Size Array selection from Combobox Array type specifier, [], ...
