Detailed Description

template<typename ExceptionT>
class ThePEG::LoopGuard< ExceptionT, void >

A LoopGuard object can be used to throw an exception if a loop is iterated too many times.

It is used by constructing an object before the loop giving the maximum number of iterations allowed and a message to be used as argument to the constructor of the exception to be thrown. Inside the loop the parenthesis is called without argument, which will increment and check an internal counter. This specialization is for the case where the exception class cannot be created with a message.
