Detailed Description

True if Test is a getter for Iterator_t, i.e., Test::get(Iterator_t) is defined.

An iterator getter returns a a value from an iterator. This is useful in generic code that may need to either extract the value from an iterator over a sequence container such as std::vector, or extract just the key or just the mapped value from an iterator over an associative container such as std::map.
