Corrade::Utility::JsonView class new in Git master
#include <Corrade/Utility/Json.h>

JSON token subtree.

Returned from Json::tokens() and JsonToken::children(). Note that, unlike with JsonObjectView and JsonArrayView, the iteration is performed on the whole subtree in a depth-first order, it doesn't iterate just the immediate children.

Public functions

auto size() -> std::size_t: Token count.
auto isEmpty() const -> bool: Whether the view is empty.
auto begin() const -> JsonIterator: Iterator to the first element.
auto cbegin() const -> JsonIterator
auto end() const -> JsonIterator: Iterator to (one item after) the last element.
auto cend() const -> JsonIterator
auto front() const -> JsonToken: First token.
auto back() const -> JsonToken: Last token.
auto operator[](std::size_t i) const -> JsonToken: Token access.

Token count.

Note that the returned value includes all nested children as well, it isn't just the count of immediate children.

Whether the view is empty.

Iterator to the first element.

If the view is empty, the iterator reports itself as valid but may point outside of the actual token data.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Iterator to (one item after) the last element.

The returned iterator reports itself as valid but may point outside of the actual token data.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

First token.

Expects there is at least one token.

Last token.

Expects there is at least one token.

Token access.

Expects that i is less than size().
