// DEPRECATED in favor of adl_predestruct with deconstruct<T>(). |
|
// A simple framework for creating objects with predestructors. |
|
// The objects must inherit from boost::signals2::predestructible, and |
|
// have their lifetimes managed by |
|
// boost::shared_ptr created with the boost::signals2::deconstruct_ptr() |
|
// function. |
