Detailed Description

template<class C>
class wibble::exception::ValOutOfRange< C >

Exception thrown when index checking fails.

This exception is to be thrown when an index checking fails, providing informations on the acceptable index range and on the offending value. The context should be a description of the index, possibly preceeded by a description of in what context did the index checking happen.

Example:

  if (age < 18)
     throw IndexOutOfRangeException("age", age, 18, 0, "obtaining driver license");

  if (i < 0 || i > 100)
    throw IndexOutOfRangeException("percentage of items sold", i, 0, 100, "checking input consistency");
