// 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.
