C++ 使用 v typedef typename

Question

可以使用using關鍵字代替使用typedef typename作為迭代器嗎？

using schedulable_ops_t = std::list<mlir::Operation*>;
typedef typename schedulable_ops_t::iterator schedulable_ops_iterator_t;

我嘗試using schedulable_ops_t::iterator = schedulable_ops_iterator_t; 但我得到一個錯誤is not a base type for type 。

Answer 1

這個記錄

using schedulable_ops_t::iterator = schedulable_ops_iterator_t;

是不正確的。 看來你的意思

using schedulable_ops_iterator_t = typename schedulable_ops_t::iterator;
