Web出于各种原因，PIMPL都是要删除不希望的公共标头依赖项。例如，使用单词 class 的C头(正确性)，增加了构建时间的大头(工作效率)，带有不良宏的头(代码脆性)。 C的可访问性(private 与 public 或 protected)无关，尽管可访问性与这些功能是否属于PIMPL类密切相关，这并非不自然：通常，这些功能将是实现 ... leach field failing
C++ 之PIMPL模式详解
WebMar 23, 2012 · In C++, separating the interface (public declarations) of a class from its implementation (private methods, members and definitions) serves several useful purposes: Implementation details are hidden, making interfaces easier to read and understand. Smaller header files with fewer dependencies means faster compile times. WebC++中函数参数的传递方式有两种：按值传递（pass-by-value）和按引用传递（pass-by-reference）。. 按值传递参数时，函数会创建一个参数的本地副本，这样就会涉及到复制参数的开销，尤其是当参数很大时，会导致性能问题。. 相反，按引用传递参数时，函数会传递 ...
