#include <jsoncons_ext/jsonpath/jsonpath.hpp>

template <typename CharT,typename Allocator>
class basic_path_element   (since 0.172.0)

Two specializations for common character types are defined:

Type	Definition
path_element	basic_path_element<char>
wpath_element	basic_path_element<wchar_t>

Objects of type basic_path_element represent an element (name or index) of a normalized path.

Member types

Type	Definition
char_type	CharT
allocator_type	Allocator
char_allocator_type	Rebound Allocator for char_type
string_type	std::basic_string<char_type,std::char_traits<char_type>,char_allocator_type>
