The QBEInteger class provides platform-independent big-endian integers.

This class was introduced in Qt 5.10.

QBEInteger Class▲

  • Header: QBEInteger

  • Since: Qt 5.10

  • CMake:

    find_package(Qt6 REQUIRED COMPONENTS Core)

    target_link_libraries(mytarget PRIVATE Qt6::Core)

  • qmake: QT += core

Detailed Description▲

The template parameter T must be a C++ integer type:

  • 8-bit: char, signed char, unsigned char, qint8, quint8

  • 16-bit: short, unsigned short, qint16, quint16, char16_t (C++11)

  • 32-bit: int, unsigned int, qint32, quint32, char32_t (C++11)

  • 64-bit: long long, unsigned long long, qint64, quint64

  • platform-specific size: long, unsigned long

  • pointer size: qintptr, quintptr, qptrdiff

Using this class may be slower than using native integers, so only use it when an exact endianness is needed.

Member Function Documentation▲

 

[explicit constexpr] QBEInteger::QBEInteger(T value)▲

Constructs a QBEInteger with the given value.

[static constexpr] QBEInteger<T> QBEInteger::max()▲

Returns the maximum (finite) value representable by the numeric type T.

[static constexpr] QBEInteger<T> QBEInteger::min()▲

Returns the minimum (finite) value representable by the numeric type T.

T QBEInteger::operator T() const▲

Returns the value of this QBEInteger as a native integer.

bool QBEInteger::operator!=(QBEInteger<T> other) const▲

Returns true if the value of this QBEInteger is not equal to the value of other.

QBEInteger<T> &QBEInteger::operator%=(T i)▲

Sets this QBEInteger to the remainder of a division by i and returns a reference to this object.

QBEInteger<T> &QBEInteger::operator&=(T i)▲

Performs a bitwise AND with i onto this QBEInteger and returns a reference to this object.

QBEInteger<T> &QBEInteger::operator*=(T i)▲

Multiplies i with this QBEInteger and returns a reference to this object.

QBEInteger<T> &QBEInteger::operator++()▲

Performs a prefix ++ (increment) on this QBEInteger and returns a reference to this object.

QBEInteger<T> &QBEInteger::operator++(int)▲

Performs a postfix ++ (increment) on this QBEInteger and returns a reference to this object.

QBEInteger<T> &QBEInteger::operator+=(T i)▲

Adds i to this QBEInteger and returns a reference to this object.

QBEInteger<T> &QBEInteger::operator--()▲

Performs a prefix – (decrement) on this QBEInteger and returns a reference to this object.

QBEInteger<T> &QBEInteger::operator--(int)▲

Performs a postfix – (decrement) on this QBEInteger and returns a reference to this object.

QBEInteger<T> &QBEInteger::operator-=(T i)▲

Subtracts i from this QBEInteger and returns a reference to this object.

QBEInteger<T> &QBEInteger::operator/=(T i)▲

Divides this QBEInteger with i and returns a reference to this object.

QBEInteger<T> &QBEInteger::operator<<=(T i)▲

Performs a right-shift by i on this QBEInteger and returns a reference to this object.

QBEInteger<T> &QBEInteger::operator=(T i)▲

Assigns i to this QBEInteger and returns a reference to this QBEInteger.

bool QBEInteger::operator==(QBEInteger<T> other) const▲

Returns true if the value of this QBEInteger is equal to the value of other.

QBEInteger<T> &QBEInteger::operator>>=(T i)▲

Performs a left-shift by i on this QBEInteger and returns a reference to this object.

QBEInteger<T> &QBEInteger::operator^=(T i)▲

Performs a bitwise XOR with i onto this QBEInteger and returns a reference to this object.

QBEInteger<T> &QBEInteger::operator|=(T i)▲

Performs a bitwise OR with i onto this QBEInteger and returns a reference to this object.
