Detailed Description

\inmodule QtCore

Since

5.15

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

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);

operator bool()

QByteArray::FromBase64Result::operator bool ( ) const

inlineexplicitnoexcept

\variable QByteArray::FromBase64Result::decoded

Contains the decoded byte array.

\variable QByteArray::FromBase64Result::decodingStatus

Contains whether the decoding was successful, expressed as a value of type QByteArray::Base64DecodingStatus.

Returns whether the decoding was successful. This is equivalent to checking whether the {decodingStatus} member is equal to QByteArray::Base64DecodingStatus::Ok.

operator*() [1/2]

QByteArray & QByteArray::FromBase64Result::operator* ( ) const

operator!=

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

friend

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

Definition at line 770 of file qbytearray.h.

operator==

bool QByteArray::FromBase64Result::operator== ( const QByteArray::FromBase64Result & lhs, const QByteArray::FromBase64Result & rhs )

friend

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.

Definition at line 759 of file qbytearray.h.

qHash()

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

related

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