如果两个std::shared_ptr互相引用,形成一个循环,那么这两个std::shared_ptr所引用的对象就无法被正确释放。例如: struct Node {std::shared_ptr<Node> sibling;};void foo() {std::shared_ptr<Node> node1(new Node);std::shared_ptr<Node> node2(new Node);node1->sibling = node2;node2->sibling ...

explicit operator bool() 允许到 bool 的显式转换 - 例如,在给定 shared_ptr<X> sp 的情况下,bool b(sp) 和static_cast<bool>(sp) 都有效 - 允许对 bool 进行布尔值可测试的“上下文转换”- 例如,if (sp)、!sp、sp && 等。 但是,explicit operator bool() 禁止隐式转换为 bool,因此不能使用 bool...
事实上,传递过后,源auto_ptr不在访问原有的对象,并且目标 auto_ptr成为了对象的唯一拥有者(但是往往auto_ptr的旧的实现即使在释放后仍然保持着对对象的所有权)。自然而然的我们可以将这种新的行为称作Transfer Semantics。 拷贝构造函数(copy construcor)和赋值操作符定义了auto_ptr的Transfer Semantics,它们用了非con...
explicit operator bool() permits explicit conversions to bool—for example, given shared_ptr<X> sp, both static_cast<bool>(sp) and bool b(sp) are valid—and Boolean-testable "contextual conversions" to bool—for example, if (sp), !sp, sp && whatever. However, explicit operator bool() ...
问向Rocksdb的CMakeLists添加gRPC依赖ENRocksDB是FaceBook起初作为实验性质开发的一个高效数据库软件，旨在充分实现快存上存储数据的服务能力。RocksDB是一个c++库，可以用来存储keys和values，且keys和values可以是任意的字节流，支持原子的读和写。除此外，RocksDB深度支持各种配置，可以在不同的生产环境（纯内存、...
The best approach is to use flatcc_builder_custom_init to provide a custom allocator and emitter object, but for simpler case or while piloting a new platform flatcc_alloc.h can be used to override runtime allocation functions. Carefully read the comments in this file if doing so. There ...
We've written custom memory allocators for the GPU to make sure that your deep learning models are maximally memory efficient. This enables you to train bigger deep learning models than before. Extensions Without Pain Writing new neural network modules, or interfacing with PyTorch's Tensor API ...
void *p = malloc(size); // Replace this with alternative allocator return (p); } void TestClass::operator delete(void *p) { free(p); // Replace this with alternative de-allocator } 所有TestClass 对象的内存分配都采用这段代码。更进一步,任何从TestClass 继承的类也都采用这一方式,除非它自己...
F Features removed when the /std:c++17 or later compiler option is specified. To re-enable these features (to ease the transition to newer language modes), use these macros: _HAS_AUTO_PTR_ETC, _HAS_FUNCTION_ALLOCATOR_SUPPORT, _HAS_OLD_IOSTREAMS_MEMBERS, and _HAS_UNEXPECTED....
