Public Types | |
using | difference_type = typename basic_json::difference_type |
a type to represent differences between iterators | |
using | iterator_category = std::bidirectional_iterator_tag |
the category of the iterator | |
using | pointer = typename std::conditional< std::is_const< U >::value, typename basic_json::const_pointer, typename basic_json::pointer >::type |
defines a pointer to the type iterated over (value_type) | |
using | reference = typename std::conditional< std::is_const< U >::value, typename basic_json::const_reference, typename basic_json::reference >::type |
defines a reference to the type iterated over (value_type) | |
using | value_type = typename basic_json::value_type |
the type of the values when the iterator is dereferenced | |
