template<typename ValueType> ValueType& get_to(ValueType& v) const noexcept( noexcept(JSONSerializer<ValueType>::from_json( std::declval<const basic_json_t&>(), v)))
Explicit type conversion between the JSON value and a compatible value. The value is filled into the input parameter by calling the json_serializer<ValueType> from_json() method.
The function is equivalent to executing
ValueType v; JSONSerializer<ValueType>::from_json(*this, v);
This overloads is chosen if:
ValueType is not basic_json,json_serializer<ValueType> has a from_json() method of the form void from_json(const basic_json&, ValueType&)ValueType : the value type to return
the input parameter, allowing chaining calls
Depends on what json_serializer<ValueType> from_json() method throws
??? example
The example below shows several conversions from JSON values to other types. There a few things to note: (1)
Floating-point numbers can be converted to integers, (2) A JSON array can be converted to a standard
`#!cpp std::vector<short>`, (3) A JSON object can be converted to C++ associative containers such as
`#cpp std::unordered_map<std::string, json>`.
```cpp
--8<-- "examples/get_to.cpp"
```
Output:
```json
--8<-- "examples/get_to.output"
```
