Member Type Documentation

enum QCborError::Code

This enum contains the possible error condition codes.

Constant	Value	Description
QCborError::NoError	0	No error was detected.
QCborError::UnknownError	1	An unknown error occurred and no further details are available.
QCborError::AdvancePastEnd	3	QCborStreamReader::next() was called but there are no more elements in the current context.
QCborError::InputOutputError	4	An I/O error with the QIODevice occurred.
QCborError::GarbageAtEnd	256	Data was found in the input stream after the last element.
QCborError::EndOfFile	257	The end of the input stream was unexpectedly reached while processing an element.
QCborError::UnexpectedBreak	258	The CBOR stream contains a Break where it is not allowed (data is corrupt and the error is not recoverable).
QCborError::UnknownType	259	The CBOR stream contains an unknown/unparsable Type (data is corrupt and the and the error is not recoverable).
QCborError::IllegalType	260	The CBOR stream contains a known type in a position it is not allowed to exist (data is corrupt and the error is not recoverable).
QCborError::IllegalNumber	261	The CBOR stream appears to be encoding a number larger than 64-bit (data is corrupt and the error is not recoverable).
QCborError::IllegalSimpleType	262	The CBOR stream contains a Simple Type encoded incorrectly (data is corrupt and the error is not recoverable).
QCborError::InvalidUtf8String	516	The CBOR stream contains a text string that does not decode properly as UTF-8 (data is corrupt and the error is not recoverable).
QCborError::DataTooLarge	1024	CBOR string, map or array is too big and cannot be parsed by Qt (internal limitation, but the error is not recoverable).
QCborError::NestingTooDeep	1025	Too many levels of arrays or maps encountered while processing the input (internal limitation, but the error is not recoverable).
QCborError::UnsupportedType	1026	The CBOR stream contains a known type that the implementation does not support (internal limitation, but the error is not recoverable).

Member Function Documentation

QString QCborError::toString() const

Returns a text string that matches the error code in this QCborError object.

Note: the string is not translated. Applications whose interface allow users to parse CBOR streams need to provide their own, translated strings.

See also QCborError::Code.

QCborError::Code QCborError::operator QCborError::Code() const

Returns the error code that this QCborError object stores.
