此外,泛型组件还可以提供异常中性保证:如果从某个模板形参(例如从 std::sort 的Compare 函数对象,或从 std::make_shared 中T 的构造函数)抛出异常,那么它会被无修改地传播给调用方。 异常对象虽然任意完整类型和指向 void 的cv 指针都能作为异常对象抛出,但所有标准库函数都以值抛出无名对象,而且这些对象的类型...
以调用 std::make_shared 或std::allocate_shared 创建shared_ptr 时,以单次分配创建控制块和被管理对象。被管理对象在控制块的数据成员中原位构造。通过 shared_ptr 的构造函数之一创建 shared_ptr 时,被管理对象和控制块只能分离分配。此情况中,控制块存储指向被管理对象的指针。 shared_ptr 直接持有的指针即是...
Likestd::make_shared, this function typically performs only one allocation, and places both theTobject and the control block in the allocated memory block (the standard recommends but does not require this, all known implementations do this). A copy ofallocis stored as part of the control blo...
