Detailed Description

Utility class for safe checking of region validity.

To use this class, construct an instance of alive_checker with any object you wish to monitor. Then use the object. Then use alive_checker::is_alive() to check if the object is still alive.

// Construct the checker
alive_checker checker(*this);
 
// Call a member function that may destroy 'this'
maybe_destroy_this();
 
// Check if 'this' is still alive
if (!checker.is_alive()) return;
