- If `m_type == value_t::object`, then `m_value.object != nullptr`.

@brief checks the class invariants
|
|
|
|
|
|
|
|
This function asserts the class invariants. It needs to be called at the
|
|
|
|
end of every constructor to make sure that created objects respect the
|
|
|
|
invariant. Furthermore, it has to be called each time the type of a JSON
|
|
|
|
value is changed, because the invariant expresses a relationship between
|
|
|
|
@a m_type and @a m_value.
|
2021-01-10 22:40:50 +01:00
|
|
|
|
|
|
|
Furthermore, the parent relation is checked for arrays and objects: If
|
|
|
|
@a check_parents true and the value is an array or object, then the
|
|
|
|
container's elements must have the current value as parent.
|
|
|
|
|
|
|
|
@param[in] check_parents whether the parent relation should be checked.
|
2021-01-14 21:56:19 +01:00
|
|
|
The value is true by default and should only be set to false
|
2021-01-10 22:40:50 +01:00
|
|
|
during destruction of objects when the invariant does not
|
|
|
|
need to hold.
