Detailed Description

template<class T, T T_MAX, T T_MIN>
class OverflowSafeInt< T, T_MAX, T_MIN >

Overflow safe template for integers, i.e.

integers that will never overflow you multiply the maximum value with 2, or add 2, or subtract something from the minimum value, etc.

Parameters:
T the type these integers are stored with.
T_MAX the maximum value for the integers.
T_MIN the minimum value for the integers.

Member Function Documentation

template<class T, T T_MAX, T T_MIN>
OverflowSafeInt& OverflowSafeInt< T, T_MAX, T_MIN >::operator*= ( const int  factor  )  [inline]

Safe implementation of multiplication.

Parameters:
factor the factor to multiply this with.
Note:
when the multiplication would yield more than T_MAX (or less than T_MIN), it will be T_MAX (respectively T_MIN).

Definition at line 77 of file overflowsafe_type.hpp.

template<class T, T T_MAX, T T_MIN>
OverflowSafeInt& OverflowSafeInt< T, T_MAX, T_MIN >::operator+= ( const OverflowSafeInt< T, T_MAX, T_MIN > &  other  )  [inline]

Safe implementation of addition.

Parameters:
other the amount to add
Note:
when the addition would yield more than T_MAX (or less than T_MIN), it will be T_MAX (respectively T_MIN).

Definition at line 46 of file overflowsafe_type.hpp.
