### jsoncons::jsonpath::basic_path_node
```cpp
#include <jsoncons_ext/jsonpath/jsonpath.hpp>
template <typename CharT> (since 0.172.0)
class basic_path_node
```
Two specializations for common character types are defined:
Type |Definition
----------|------------------------------
path_node |`basic_path_node<char>`
wpath_node |`basic_path_node<wchar_t>`
Objects of type `basic_path_node` represent a normalized path as a
singly linked list where each node has a pointer to its (shared) parent
node.
#### Member types
Type |Definition
------------|------------------------------
char_type | `CharT`
string_view_type | `jsoncons::basic_string_view<char_type>`
#### Constructors
basic_path_node(); (1)
basic_path_node(const basic_path_node* parent,
const string_view_type& name); (2)
basic_path_node(const basic_path_node* parent,
std::size_t index); (3)
basic_path_node(const basic_path_node&); (4)
(1) Constructs an empty `basic_path_node` with a null parent
representing the root of a path.
(2) Constructs a `basic_path_node` from a name.
(3) Constructs a `basic_path_node` from an index.
(4) Copy constructor
#### operator=
basic_path_node& operator=(const basic_path_node&);
#### Accessors
const basic_path_node* parent() const;
Returns the parent of a path node
std::size_t size() const;
Returns the number of nodes in the path.
path_node_kind node_kind() const;
Returns the kind of the node
const string_view_type& name() const;
std::size_t index() const;
#### Non-member functions
template <typename CharT,typename Allocator = std::allocator<CharT>>
std::basic_string<CharT, std::char_traits<CharT>, Allocator> to_basic_string(const basic_path_node<CharT>& location,
const Allocator& alloc = Allocator())
Returns a normalized path
std::string to_string(const path_node& path)
std::wstring to_wstring(const wpath_node& path)
