详细描述

模板参数 T 必须是 C++ 整数类型：

• 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

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

QBEInteger:: QBEInteger ( T value )

Constructs a QBEInteger with the given value .

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

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

[static] 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 作为本机整数。

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

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