## Detailed Description

### template<typename BasicJsonType>
class nlohmann::json_pointer< BasicJsonType >

A JSON pointer defines a string syntax for identifying a specific value within a JSON document. It can be used with functions `at` and `operator[]`. Furthermore, JSON pointers are the base for JSON patches.
