FromBase64Result Class

class QByteArray::FromBase64Result

The QByteArray::FromBase64Result class holds the result of a call to QByteArray::fromBase64Encoding. More...

This class was introduced in Qt 5.15.

Public Functions

bool operator bool() const
const QByteArray &operator*() const

Public Variables

QByteArray decoded
QByteArray::Base64DecodingStatus decodingStatus
size_t qHash(const QByteArray::FromBase64Result &key, size_t seed = 0)
bool operator!=(const FromBase64Result &lhs, const FromBase64Result &rhs)
bool operator==(const FromBase64Result &lhs, const FromBase64Result &rhs)

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

size_t qHash(const QByteArray::FromBase64Result &key, size_t seed = 0)

Returns the hash value for key, using seed to seed the calculation.

bool operator!=(const FromBase64Result &lhs, const FromBase64Result &rhs)

Returns true if lhs and rhs are different, otherwise returns false.

bool operator==(const FromBase64Result &lhs, const 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.
