* QCborStreamReader: make sure setDevice() clears the last errorThiago Macieira2018-11-081-0/+2
| | | | | | | | | | | | | | The unit tests weren't running into this problem because the every setDevice() was preceded by the object being initialized with the exact same data, so there was never a previous error state. I've only changed a couple of tests, left the other setDevice() unchanged so we test both behaviors.

* Doc: Move literal code block to a separate fileCristian Maureira-Fredes2018-10-151-279/+30
| | | | | | | | | | | We need to override this snippet for the documentation we generate for Qt for Python, and it is easier to have it on a separate file.

* qdoc: Fix remaining qdoc warnings for QCborxxx classesMartin Smith2018-08-171-2/+2
| | | | | | | | | | Several \fn commands are added for functions and operators that were not documented. A few qdoc warnings remain in qcborstream.cpp, but these are because an enum class was used, and qdoc doesn't yet handle those correctly all the time.

* CBOR: Use "noexcept" directlyThiago Macieira2018-07-141-3/+3
| | | | | | | | | | | All supported compilers support it. Doing this just for the new API. We should do it throughout Qt, but only if it won't interfere with the header review.

* CBOR: Add QDebug operators for the Qt CBOR value-like typesThiago Macieira2018-07-041-0/+113
| | | | | | | | | | I added a function that returns the string identifiers for QCborKnownTags and QCborSimpleType, in order to facilitate writing a QTest::toString for those types, as neither enum is part of a Q_OBJECT or Q_GADGET class.

* QCborStreamReader: use QByteArray directly if possibleThiago Macieira2018-06-061-62/+122
| | | | | | | | | | | | | | | QIODevice represents considreable overhead, even with just QBuffer, for parsing simple things. Benchmarking showed it was spending 25% of the parsing time inside one QIODevice function or another. So this commit accomplishes two things: 1) it increases the buffer size from 9 bytes to up to 256, which should reduce the number of calls into the QIODevice 2) if the source data is a QByteArray, then use it directly and bypass the QIODevice, thus increasing performance considerably Change-Id: I56b444f9d6274221a3b7fffd150c531c9d28e54b Reviewed-by: Edward Welbourne <edward.welbourne@qt.io>

CBOR is the Concise Binary Object Representation, a very compact form of binary data encoding that is compatible with JSON. It was created by the IETF Constrained RESTful Environments (CoRE) WG[1] and has since been used in many new RFCs by that group, especially COSE[2], and is meant to be used alongside CoAP[3]. This API is a very simple, thin wrapper around TinyCBOR[4]. See RFC 7049 <http://tools.ietf.org/html/rfc7049>.
