SafeInt::SafeInt
The latest version of this topic can be found at SafeInt::SafeInt.
Constructs a SafeInt object.
Syntax
SafeInt() throw
SafeInt (
const T& i
) throw ()
SafeInt (
bool b
) throw ()
template <typename U>
SafeInt (
const SafeInt <U, E>& u
)
I template <typename U>
SafeInt (
const U& i
)
Parameters
[in] i
The value for the new SafeInt object. This must be a parameter of type T or U, depending on the constructor.
[in] b
The Boolean value for the new SafeInt object.
[in] u
A SafeInt of type U. The new SafeInt object will have the same value as u, but will be of type T.
U
The type of data stored in the SafeInt. This can be either a Boolean, character, or integer type. If it is an integer type, it can be signed or unsigned and be between 8 and 64 bits.
Remarks
For more information about the template types T and E, see SafeInt Class.
The input parameter for the constructor, i or u, must be a Boolean, character, or integer type. If it is another type of parameter, the SafeInt class calls static_assert to indicate an invalid input parameter.
The constructors that use the template type U automatically convert the input parameter to the type specified by T. The SafeInt class converts the data without any loss of data. It reports to the error handler E if it cannot convert the data to type T without data loss.
If you create a SafeInt from a Boolean parameter, you need to initialize the value immediately. You cannot construct a SafeInt using the code SafeInt<bool> sb;. This will generate a compile error.
