Detailed Description

\inmodule QtCore

\reentrant

Since: 5.12

The QCborMap class is used to hold an associative container representable in CBOR.

This class can be used to hold an associative container in CBOR, a map between a key and a value type. CBOR is the Concise Binary Object Representation, a very compact form of binary data encoding that is a superset of JSON. It was created by the IETF Constrained RESTful Environments (CoRE) WG, which has used it in many new RFCs. It is meant to be used alongside the \l{RFC 7252}{CoAP protocol}.

Unlike JSON and \l QVariantMap, CBOR map keys can be of any type, not just strings. For that reason, QCborMap is effectively a map between QCborValue keys to QCborValue value elements.

However, for all member functions that take a key parameter, QCborMap provides overloads that will work efficiently with integers and strings. In fact, the use of integer keys is encouraged, since they occupy fewer bytes to transmit and are simpler to encode and decode. Newer protocols designed by the IETF CoRE WG to work specifically with CBOR are known to use them.

QCborMap is not sorted, because of that, searching for keys has linear complexity (O(n)). QCborMap actually keeps the elements in the order that they were inserted, which means that it is possible to make sorted QCborMaps by carefully inserting elements in sorted order. CBOR does not require sorting, but recommends it.

QCborMap can also be converted to and from QVariantMap and QJsonObject. However, when performing the conversion, any non-string keys will be stringified using a one-way method that the conversion back to QCborMap will not undo.

◆ compare()

int QCborMap::compare ( const QCborMap & other ) const

noexcept

Compares this map and other, comparing each element in sequence, and returns an integer that indicates whether this map should be sorted prior to (if the result is negative) or after other (if the result is positive).

If this function returns 0, the two maps are equal and contain the same elements.

Note that CBOR maps are unordered, which means that two maps containing the very same pairs but in different order will still compare differently. To avoid this, it is recommended to insert elements into the map in a predictable order, such as by ascending key value. In fact, maps with keys in sorted order are required for Canonical CBOR representation.

If the map contains no such key, this function does nothing.

If the map contains more than one key equal to key, it is undefined which one this function will remove. QCborMap does not allow inserting duplicate keys, but it is possible to create such a map by decoding a CBOR stream with them. They are usually not permitted and having duplicate keys is usually an indication of a problem in the sender.

◆ toCborValue()

QCborValue QCborMap::toCborValue ( ) const

inline

Explicitly constructs a \l QCborValue object that represents this map.

This function is usually not necessary since QCborValue has a constructor for QCborMap, so the conversion is implicit.

Converting QCborMap to QCborValue allows it to be used in any context where QCborValues can be used, including as keys and mapped types in QCborMap, as well as QCborValue::toCbor().

◆ toJsonObject()

QJsonObject QCborMap::toJsonObject ( ) const

Recursively converts every \l QCborValue value in this map to JSON using QCborValue::toJsonValue() and creates a string key for all keys that aren't strings, then returns the corresponding QJsonObject composed of those associations.

Please note that CBOR contains a richer and wider type set than JSON, so some information may be lost in this conversion. For more details on what conversions are applied, see QCborValue::toJsonValue().

◆ toVariantHash()

QVariantHash QCborMap::toVariantHash ( ) const

Converts the CBOR values to QVariant using QCborValue::toVariant() and "stringifies" all the CBOR keys in this map, returning the QVariantHash that results from that association list.

QVariantMaps have string keys, unlike CBOR, so the conversion of a QCborMap to QVariantMap will imply a step of "stringification" of the key values. See QCborMap::toJsonObject() for details.

In addition, the conversion to \l QVariant is not completely lossless. Please see the documentation in QCborValue::toVariant() for more information.

◆ value() [2/5]

QCborValue QCborMap::value ( const QCborValue & key ) const

inline

Returns the QCborValue element in this map that corresponds to key key, if there is one.

If the map does not contain key key, this function returns a QCborValue containing an undefined value. For that reason, it is not possible with this function to tell apart the situation where the key was not present from the situation where the key was mapped to an undefined value.

If the map contains more than one key equal to key, it is undefined which one this function will return. QCborMap does not allow inserting duplicate keys, but it is possible to create such a map by decoding a CBOR stream with them. They are usually not permitted and having duplicate keys is usually an indication of a problem in the sender.

◆ value() [4/5]

QCborValue QCborMap::value ( qint64 key ) const

inline

Returns the QCborValue element in this map that corresponds to key key, if there is one.

CBOR recommends using integer keys, since they occupy less space and are simpler to encode and decode.

If the map does not contain key key, this function returns a QCborValue containing an undefined value. For that reason, it is not possible with this function to tell apart the situation where the key was not present from the situation where the key was mapped to an undefined value.

If the map contains more than one key equal to key, it is undefined which one the return from function will reference. QCborMap does not allow inserting duplicate keys, but it is possible to create such a map by decoding a CBOR stream with them. They are usually not permitted and having duplicate keys is usually an indication of a problem in the sender.
