TArrowWrapper

Navigation

API > API/Runtime > API/Runtime/Core

Wrapper type for Iterators that return a structure by value from operator*, and want to support Iter->Property to behave the same as (Iter).Property. When returning a structure by reference, operator automatically handles -> as well, but when returning by value it does not.

Example: struct FIterator { public: ... // The problematic return-by-value structure from operator* // Without operator->, (Iter).Key compiles but Iter->Key does not. TPair operator() const;

// TArrowWrapper takes the value from operator* and allows -> to access it. TArrowWrapper> operator->() const; };
