Java有一个内置的接口更加完善与强大,其与我们实现的 OurComparable 相似,且支持泛型 使用:只需将 T 替换成 Dog 即可 6. Comparator 考虑一下Java如何实现函数回调(callback),在python中,使用高阶函数显示回调,compare作为参数传入 def print_larger(x, y, compare, stringify): if compare(x, y): return str...

In addition to the operator expressions demonstrated in the previous examples, the library supports almost all forms of expressions in C++ and can make them polymorphic. Specifically,macro PRO_DEF_MEM_DISPATCH: Defines a dispatch type for member function call expressions, providing accessibility as ...
