bool operator!=(const_reference lhs, const_reference rhs) noexcept;
template<typename ScalarType>
bool operator!=(const_reference lhs, const ScalarType rhs) noexcept;
template<typename ScalarType>
bool operator!=(ScalarType lhs, const const_reference rhs) noexcept;
Compares two JSON values for inequality by calculating #!cpp !(lhs == rhs).
Template parameters
ScalarType- a scalar type according to
std::is_scalar<ScalarType>::value
Parameters
lhs(in)- first value to consider
rhs(in)- second value to consider
Return value
whether the values lhs and rhs are not equal
Exception safety
No-throw guarantee: this function never throws exceptions.
Complexity
Linear.
Examples
??? example
The example demonstrates comparing several JSON types.
```cpp
--8<-- "examples/operator__notequal.cpp"
```
Output:
```json
--8<-- "examples/operator__notequal.output"
```
??? example
The example demonstrates comparing several JSON types against the null pointer (JSON `#!json null`).
```cpp
--8<-- "examples/operator__notequal__nullptr_t.cpp"
```
Output:
```json
--8<-- "examples/operator__notequal__nullptr_t.output"
```
