nlohmann::json_pointer
template<typename RefStringType>
class json_pointer;
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.
Template parameters
RefStringType
- the string type used for the reference tokens making up the JSON pointer
Notes
For backwards compatibility RefStringType
may also be a specialization of basic_json
in
which case string_t
will be deduced as basic_json::string_t
. This feature is deprecated
and may be removed in a future major version.
Member types
- string_t - the string type used for the reference tokens
Member functions
- (constructor)
- to_string - return a string representation of the JSON pointer
- operator string_t - return a string representation of the JSON pointer
- operator/= - append to the end of the JSON pointer
- operator/ - create JSON Pointer by appending
- parent_pointer - returns the parent of this JSON pointer
- pop_back - remove last reference token
- back - return last reference token
- push_back - append an unescaped token at the end of the pointer
- empty - return whether pointer points to the root document
