Function old

Function old_failure

boost::contract::old_failure — Call failure handler for old value copies at body.

Synopsis

// In header: <boost/contract/core/exception.hpp>


void old_failure(from where);

Description

This is often called only internally by this library.

Throws: This can throw in case programmers specify a failure handler that throws exceptions on contract assertion failures (not the default).

Parameters:

where

Operation that failed the old value copy (e.g., this might be useful to program failure handler functors that never throw from destructors, not even when they are programmed by users to throw exceptions instead of terminating the program).
