Function Documentation
[deprecated in 6.12] const char *QBinaryJson::toRawData(const QJsonDocument &document, int *size)
This function is deprecated since 6.12. We strongly advise against using it in new code.
Use toBinaryData() instead.
Returns the raw binary representation of document. size will contain the size of the returned data.
This method is useful to e.g. stream the JSON document in its binary form to a file.
Warning: In Qt 6, unlike Qt 5, the caller takes ownership of the returned data and must release it with free() once it is not needed anymore. Use toBinaryData() to get the binary representation in a QByteArray, which manages the memory automatically.
Note: The binary JSON encoding is only retained for backwards compatibility. It is undocumented and restrictive in the maximum size of JSON documents that can be encoded. Qt JSON types can be converted to Qt CBOR types, which can in turn be serialized into the CBOR binary format and vice versa. The CBOR format is a well-defined and less restrictive binary representation for a superset of JSON.
