The class is not limited to parallel preconditioners. To reflect this we rename it to AdditionalObjectDeleter. As it will also be used for the parallel interleaved version we move the class to a separate header.

//! \brief A custom deleter that will delete an additional object, too.

|
|
//! In dune-istl most parallel preconditioners hold a reference to
|
|
//! a sequential preconditioner.
|
|
//! In CPRPreconditioner and NewtonIterationBlackoilInterleaved we use unique_ptr
|
|
//! for the memory management.
|
|
//! Ergo we need to construct the sequential preconditioner with new and
|
|
//! make sure that it gets deleted together with the enclosing parallel
|
|
//! preconditioner. Therefore this deleter stores a pointer to it and deletes
|
|
//! it during destruction.
|
|
//! \tparam The type of the additional object to be deleted.
