Detailed Description

\inmodule QtCore

\reentrant

Since: 5.12

The QCborArray class is used to hold an array of CBOR elements.

\compares strong \compareswith strong QCborValueConstRef \endcompareswith

This class can be used to hold one sequential container in CBOR (an array). 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}.

QCborArray is very similar to \l QVariantList and \l QJsonArray and its API is almost identical to those two classes. It can also be converted to and from those two, though there may be loss of information in some conversions.

Explicitly construcuts a \l QCborValue object that represents this array.

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

Converting QCborArray to QCborValue allows it to be used in any context where QCborValues can be used, including as items in QCborArrays and as keys and mapped types in QCborMap. Converting an array to QCborValue allows access to QCborValue::toCbor().

◆ toJsonArray()

QJsonArray QCborArray::toJsonArray ( ) const

Recursively converts every \l QCborValue element in this array to JSON using QCborValue::toJsonValue() and returns the corresponding QJsonArray composed of those elements.

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().

◆ toVariantList()

QVariantList QCborArray::toVariantList ( ) const

Recursively converts each \l QCborValue in this array using QCborValue::toVariant() and returns the QVariantList composed of the converted items.

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