Detailed Description
A random access iterator over the entries of an object, in the sorted order of their keys. key() returns the key and the dereferenced value is a QJsonValueConstRef.

Member Function Documentation
QJsonObject::const_iterator::const_iterator()
Creates an iterator that refers to no object.
QJsonObject::const_iterator::const_iterator(const QJsonObject *object, qsizetype index)
Creates an iterator that refers to entry index of object.
QJsonObject::const_iterator::const_iterator(const iterator &other)
Creates a const iterator that refers to the entry of other.
QString QJsonObject::const_iterator::key() const
Returns the key of the current entry.
QAnyStringView QJsonObject::const_iterator::keyView() const
Returns a view of the key of the current entry, without copying it. The view is valid until a key is inserted into the object or removed from it.
This function was introduced in 6.10.
See also key().
bool QJsonObject::const_iterator::operator!=(const const_iterator &other) const
Returns true if other refers to another entry.
QJsonValueConstRef QJsonObject::const_iterator::operator*() const
Returns a reference to the value of the current entry.
const_iterator QJsonObject::const_iterator::operator+(qsizetype j) const
Returns an iterator j entries after this one.
const_iterator & QJsonObject::const_iterator::operator++()
Advances the iterator to the next entry and returns it.
const_iterator QJsonObject::const_iterator::operator++(int)
This is an overloaded function.
Advances the iterator and returns its previous position.
const_iterator & QJsonObject::const_iterator::operator+=(qsizetype j)
Advances the iterator by j entries and returns it.
const_iterator QJsonObject::const_iterator::operator-(qsizetype j) const
This is an overloaded function.
Returns an iterator j entries before this one.
qsizetype QJsonObject::const_iterator::operator-(const const_iterator &other) const
This is an overloaded function.
Returns the number of entries between other and this iterator.
const_iterator & QJsonObject::const_iterator::operator--()
Moves the iterator to the previous entry and returns it.
const_iterator QJsonObject::const_iterator::operator--(int)
This is an overloaded function.
Moves the iterator back and returns its previous position.
const_iterator & QJsonObject::const_iterator::operator-=(qsizetype j)
Moves the iterator back by j entries and returns it.
QJsonRefArrow<QJsonValueConstRef> QJsonObject::const_iterator::operator->() const
Returns a pointer-like helper for the value of the current entry.
bool QJsonObject::const_iterator::operator<(const const_iterator &other) const
Returns true if this iterator is before other.
bool QJsonObject::const_iterator::operator<=(const const_iterator &other) const
Returns true if this iterator is before or at the same position as other.
bool QJsonObject::const_iterator::operator==(const const_iterator &other) const
Returns true if other refers to the same entry.
bool QJsonObject::const_iterator::operator>(const const_iterator &other) const
Returns true if this iterator is after other.
bool QJsonObject::const_iterator::operator>=(const const_iterator &other) const
Returns true if this iterator is after or at the same position as other.
QJsonValueConstRef QJsonObject::const_iterator::operator[](qsizetype j) const
Returns a reference to the value of the entry j positions after the current one.
QJsonValueConstRef QJsonObject::const_iterator::value() const
Returns a reference to the value of the current entry.
