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.
