Detailed Description

template<typename T>
class gko::copy_back_deleter< T >

A copy_back_deleter is a type of deleter that copies the data to an internally referenced object before performing the deletion.

The deleter will use the copy_from method to perform the copy, and then delete the passed object using the delete keyword. This kind of deleter is useful when temporarily copying an object with the intent of copying it back once it goes out of scope.

There is also a specialization for constant objects that does not perform the copy, since a constant object couldn't have been changed.

Template Parameters

T	the type of object being deleted
