The cbordump utility can output in + CBOR diagnostic notation (which is similar to JSON), or it can have a + verbose output where each byte input is displayed with the encoding beside + it. This example shows how to use the QCborStreamReader class directly to + parse CBOR content. + + \sa QCborStreamReader + + \image cbordump.png + + \section1 The Cbordumper Class + + The Cbordumper class contains a QCborStreamReader object that is + initialized using the QFile object argument passed to the CborDumper + constructor. Based on the arguments the dump function calls either + dumpOne() or dumpOneDetailed() to dump the contents to stdout, + + \snippet serialization/cbordump/main.cpp 0 + + \section2 The dumpOne() Function + + The type() function of the QCborStreamReader is used in a switch statement + to print out for each type. If the type is an array or map, the content is + iterated upon, and for each entry the dumpOne() function is called + recursively with a higher indentation argument. If the type is a tag, it + is printed out and dumpOne() is called once without increasing the + indentation argument. + + \section2 The dumpOneDetailed() Function + + This function dumps out both the incoming bytes and the decoded contents + on the same line. It uses lambda functions to print out the bytes and + decoded content, but otherwise has a similar structure as dumpOne(). + + \section1 CborDescription + + The tagDescriptions table, describing the CBOR-tags available, is + automatically generated from an XML-file available from the iana.org + website. + + \sa {CBOR Support in Qt} + */ |
