```cpp
|
||
|
|
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 whether one JSON value `lhs` is less than or equal to another JSON value `rhs` by calculating
|
||
|
|
`#cpp !(rhs < lhs)`.
|
||
|
|
|
||
|
|
## 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 `lhs` is less than or equal to `rhs`
|
||
|
|
|
||
|
|
## Exception safety
|
||
|
|
|
||
|
|
No-throw guarantee: this function never throws exceptions.
|
||
|
|
|
||
|
|
## Complexity
|
||
|
|
|
||
|
|
Linear.
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
??? example
|
||
|
|
|
||
|
|
The example demonstrates comparing several JSON types.
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
--8<-- "examples/operator__lessequal.cpp"
|
||
|
|
```
|
||
|
|
|
||
|
|
Output:
|
||
|
|
|
||
|
|
```json
|
||
|
|
--8<-- "examples/operator__lessequal.output"
|
||
|
|
```
