Public Member Functions | |
Json_wrapper_object_iterator (const Json_wrapper &wrapper, bool begin) | |
Creates an iterator that iterates over all members of the given Json_wrapper, if it wraps a JSON object. More... | |
Json_wrapper_object_iterator ()=default | |
Forward iterators must be default constructible. More... | |
Json_wrapper_object_iterator & | operator++ () |
Advances the iterator to the next element. More... | |
const Json_wrapper_object_iterator | operator++ (int) |
Advances the iterator to the next element and returns an iterator that points to the current element (post-increment operator). More... | |
bool | operator== (const Json_wrapper_object_iterator &other) const |
Checks two iterators for equality. More... | |
bool | operator!= (const Json_wrapper_object_iterator &other) const |
Checks two iterators for inequality. More... | |

reference | operator* () |
Private Member Functions | |
bool | is_dom () const |
Returns true if iterating over a DOM. More... | |
void | initialize_current_member () |
Fill m_current_member with the key and value of the current member. More... | |
Private Attributes | |
value_type | m_current_member |
Pair holding the key and value of the member pointed to by the iterator. More... | |
bool | m_current_member_initialized {false} |
True if m_current_member is initialized. More... | |
const json_binary::Value * | m_binary_value |
The binary JSON object being iterated over, or nullptr for DOMs. More... | |
size_t | m_current_element_index |
The index of the current member in the binary JSON object. More... | |

Json_wrapper_object_iterator::Json_wrapper_object_iterator | ( | const Json_wrapper & | wrapper, |
bool | begin | ||
) |
Creates an iterator that iterates over all members of the given Json_wrapper, if it wraps a JSON object.
If the wrapper does not wrap a JSON object, the result is undefined.
