Detailed Description
The QBEInteger class provides platform-independent big-endian integers.
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
Note: Using this class may be slower than using native integers, so only use it when an exact endian is needed.
Member Function Documentation
QBEInteger::QBEInteger(T value)
Constructs a QBEInteger with the given value.
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+=(T i)
Adds i to 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.
