# nlohmann::basic_json::get
|
||||
|
||||
```
|

// (1)
|
||||
template<typename ValueType>
|
||||
ValueType get() const noexcept(
|
||||
noexcept(JSONSerializer<ValueType>::from_json(
|
||||
std::declval<const basic_json_t&>(), std::declval<ValueType&>())));
|
||||
|
||||
// (2)
|
||||
template<typename BasicJsonType>

PointerType get_ptr();
|
||||
|
||||
template<typename PointerType>
|
||||
constexpr const PointerType get_ptr() const noexcept;
|
||||
```
|
||||
|
||||
1. Explicit type conversion between the JSON value and a compatible value which is [CopyConstructible](https://en.cppreference.com/w/cpp/named_req/CopyConstructible) and [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible). The value is converted by calling the `json_serializer<ValueType>` `from_json()` method.
|
||||
|
||||
The function is equivalent to executing
|
||||
|
||||
```
|
||||
ValueType ret;
|
||||
JSONSerializer<ValueType>::from_json(*this, ret);
|
||||
return ret;
|
||||
```
|
||||
|
||||
This overload 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&)`, and
|
||||
- `json_serializer<ValueType>` does not have a `from_json()` method of the form `ValueType from_json(const basic_json&)`
|
||||
|
||||
If the type is **not** [CopyConstructible](https://en.cppreference.com/w/cpp/named_req/CopyConstructible) and **not** [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible), the value is converted by calling the `json_serializer<ValueType>` `from_json()` method.
|
||||
|
||||
The function is then equivalent to executing
|
||||
|
||||
```
|
||||
return JSONSerializer<ValueTypeCV>::from_json(*this);
|
||||
```
|
||||
|
||||
This overload is chosen if:
|
||||
|
||||
- `ValueType` is not `basic_json` and
|
||||
- `json_serializer<ValueType>` has a `from_json()` method of the form `ValueType from_json(const basic_json&)`
|
||||
|
||||
If `json_serializer<ValueType>` has both overloads of `from_json()`, the latter one is chosen.
|
||||
|
||||
1. Overload for `basic_json` specializations. The function is equivalent to executing
|
||||
|
||||
```
|
||||
return *this;
|
||||
```
|
||||
|
||||
1. Explicit pointer access to the internally stored JSON value. No copies are made.
|
||||
|
||||
## Template parameters
|
||||
|
||||
`ValueType` : the value type to return
|
||||
|
||||
`BasicJsonType` : a specialization of `basic_json`
|
||||
|
||||
`PointerType` : pointer type; must be a pointer to [`array_t`](https://json.nlohmann.me/api/basic_json/array_t/index.md), [`object_t`](https://json.nlohmann.me/api/basic_json/object_t/index.md), [`string_t`](https://json.nlohmann.me/api/basic_json/string_t/index.md), [`boolean_t`](https://json.nlohmann.me/api/basic_json/boolean_t/index.md), [`number_integer_t`](https://json.nlohmann.me/api/basic_json/number_integer_t/index.md), or [`number_unsigned_t`](https://json.nlohmann.me/api/basic_json/number_unsigned_t/index.md), [`number_float_t`](https://json.nlohmann.me/api/basic_json/number_float_t/index.md), or [`binary_t`](https://json.nlohmann.me/api/basic_json/binary_t/index.md). Other types will not compile.
|
||||
|
||||
## Return value
|
||||
|
||||
1. copy of the JSON value, converted to `ValueType`
|
||||
1. a copy of `*this`, converted into `BasicJsonType`
|
||||
1. pointer to the internally stored JSON value if the requested pointer type fits to the JSON value; `nullptr` otherwise
|
||||
|
||||
## Exceptions
|
||||
|
||||
Depends on what `json_serializer<ValueType>` `from_json()` method throws
|
||||
|
||||
## Complexity
|
||||
|
||||
Depends on the `json_serializer<ValueType>::from_json()` implementation for overloads (1) and (2); constant for overload (3).
|
||||
|
||||
## Notes
|
||||
|
||||
Undefined behavior for pointers
|
||||
|
||||
Writing data to the pointee (overload 3) of the result yields an undefined state.
|
||||
|
||||
Undefined behavior for numeric conversions
|
||||
|
||||
Conversions between numeric types are performed by the corresponding `from_json()` implementation using the target C++ type. When converting between numeric types, the library does not check whether the source value is representable by the target type.
|
||||
|
||||
If the source value is outside the range of the target type, the behavior is the same as the corresponding C++ conversion. In particular, converting a floating-point value to an integer type that cannot represent the value results in undefined behavior.
|
||||
|
||||
See [Number conversion](https://json.nlohmann.me/features/types/number_handling/#number-conversion) for more information.
|
||||
|
||||
## Examples
|
||||
|
||||
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 `std::vector<short>`, (3) A JSON object can be converted to C++ associative containers such as `std::unordered_map<std::string, json>`.
|
||||
|
||||
```
|
||||
#include <iostream>
|
||||
#include <unordered_map>
|
||||
#include <nlohmann/json.hpp>
|
||||
|
||||
using json = nlohmann::json;
|
||||
|
||||
int main()
|
||||
{
|
||||
// create a JSON value with different types
|
||||
json json_types =
|
||||
{
|
||||
{"boolean", true},
|
||||
{
|
||||
"number", {
|
||||
{"integer", 42},
|
||||
{"floating-point", 17.23}
|
||||
}
|
||||
},
|
||||
{"string", "Hello, world!"},
|
||||
{"array", {1, 2, 3, 4, 5}},
|
||||
{"null", nullptr}
|
||||
};
|
||||
|
||||
// use explicit conversions
|
||||
auto v1 = json_types["boolean"].get<bool>();
|
||||
auto v2 = json_types["number"]["integer"].get<int>();
|
||||
auto v3 = json_types["number"]["integer"].get<short>();
|
||||
auto v4 = json_types["number"]["floating-point"].get<float>();
|
||||
auto v5 = json_types["number"]["floating-point"].get<int>();
|
||||
auto v6 = json_types["string"].get<std::string>();
|
||||
auto v7 = json_types["array"].get<std::vector<short>>();
|
||||
auto v8 = json_types.get<std::unordered_map<std::string, json>>();
|
||||
|
||||
// print the conversion results
|
||||
std::cout << v1 << '\n';
|
||||
std::cout << v2 << ' ' << v3 << '\n';
|
||||
std::cout << v4 << ' ' << v5 << '\n';
|
||||
std::cout << v6 << '\n';
|
||||
|
||||
for (auto i : v7)
|
||||
{
|
||||
std::cout << i << ' ';
|
||||
}
|
||||
std::cout << "\n\n";
|
||||
|
||||
for (auto i : v8)
|
||||
{
|
||||
std::cout << i.first << ": " << i.second << '\n';
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Output:
|
||||
|
||||
```
|
||||
1
|
||||
42 42
|
||||
17.23 17
|
||||
Hello, world!
|
||||
1 2 3 4 5
|
||||
|
||||
string: "Hello, world!"
|
||||
number: {"floating-point":17.23,"integer":42}
|
||||
null: null
|
||||
boolean: true
|
||||
array: [1,2,3,4,5]
|
||||
```
|
||||
|
||||
Example
|
||||
|
||||
The example below shows how pointers to internal values of a JSON value can be requested. Note that no type conversions are made and a `#cpp nullptr` is returned if the value and the requested pointer type does not match.
|
||||
|
||||
```
|
||||
#include <iostream>
|
||||
#include <nlohmann/json.hpp>
|
||||
|
||||
using json = nlohmann::json;
|
||||
|
||||
int main()
|
||||
{
|
||||
// create a JSON number
|
||||
json value = 17;
|
||||
|
||||
// explicitly getting pointers
|
||||
auto p1 = value.get<const json::number_integer_t*>();
|
||||
auto p2 = value.get<json::number_integer_t*>();
|
||||
auto p3 = value.get<json::number_integer_t* const>();
|
||||
auto p4 = value.get<const json::number_integer_t* const>();
|
||||
auto p5 = value.get<json::number_float_t*>();
|
||||
|
||||
// print the pointees
|
||||
std::cout << *p1 << ' ' << *p2 << ' ' << *p3 << ' ' << *p4 << '\n';
|
||||
std::cout << std::boolalpha << (p5 == nullptr) << '\n';
|
||||
}
|
||||
```
|
||||
|
||||
Output:
|
||||
|
||||
```
|
||||
17 17 17 17
|
||||
true
|
||||
```
