Detailed Description
Objects of this class can be used to check whether the conversion was successful, and if so, retrieve the decoded QByteArray. The conversion operators defined for QByteArray::FromBase64Result make its usage straightforward:
void process(const QByteArray &); if (auto result = QByteArray::fromBase64Encoding(encodedData)) process(*result);
Alternatively, it is possible to access the conversion status and the decoded data directly:
auto result = QByteArray::fromBase64Encoding(encodedData); if (result.decodingStatus == QByteArray::Base64DecodingStatus::Ok) process(result.decoded);
See also QByteArray::fromBase64.
Member Function Documentation
bool FromBase64Result::operator bool() const
Returns whether the decoding was successful. This is equivalent to checking whether the decodingStatus
member is equal to QByteArray::Base64DecodingStatus::Ok.
const QByteArray &FromBase64Result::operator*() const
Returns the decoded byte array.
Member Variable Documentation
QByteArray FromBase64Result::decoded
Contains the decoded byte array.
QByteArray::Base64DecodingStatus FromBase64Result::decodingStatus
Contains whether the decoding was successful, expressed as a value of type QByteArray::Base64DecodingStatus.
Related Non-Members
uint qHash(const QByteArray::FromBase64Result &key, uint seed = 0)
Returns the hash value for key, using seed to seed the calculation.
bool operator!=(const QByteArray::FromBase64Result &lhs, const QByteArray::FromBase64Result &rhs)
Returns true
if lhs and rhs are different, otherwise returns false
.
bool operator==(const QByteArray::FromBase64Result &lhs, const QByteArray::FromBase64Result &rhs)
Returns true
if lhs and rhs are equal, otherwise returns false
.
lhs and rhs are equal if and only if they contain the same decoding status and, if the status is QByteArray::Base64DecodingStatus::Ok, if and only if they contain the same decoded data.
