basic_json::operator!=

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.

Example

The example demonstrates comparing several JSON types.

--8<-- "examples/operator__notequal.cpp"

Output:

--8<-- "examples/operator__notequal.output"
