template< template< typename U, typename V, typename... Args > class ObjectType = std::map, template< typename U, typename... Args > class ArrayType = std::vector, class StringType = std::string, class BooleanType = bool, class NumberIntegerType = std::int64_t, class NumberUnsignedType = std::uint64_t, class NumberFloatType = double, template< typename U > class AllocatorType = std::allocator, template< typename T, typename SFINAE= void > class JSONSerializer = adl_serializer>
Finds an element in a JSON object with key equivalent to key. If the element is not found or the JSON value is not an object, end() is returned.
- Note
- This method always returns end() when executed on a JSON type that is not an object.
- Parameters
-
[in] | key | key value of the element to search for |
- Returns
- Iterator to an element with key equivalent to key. If no such element is found or the JSON value is not an object, past-the-end (see end()) iterator is returned.
- Complexity\n Logarithmic in the size of the JSON object.
- Example\n The example shows how
find() is used. \n @includelineno find__key_type.cpp \n Output (play with this example @htmlinclude find__key_type.link):\n @verbinclude find__key_type.output \n The example code above can be translated with @verbatim g++ -std=c++11 -Isrc doc/examples/find__key_type.cpp -o find__key_type @endverbatim
- Since
- version 1.0.0
