Detailed Description
class AMP::enable_shared_from_this< T >
Enhancement of std::enable_shared_from_this.
This class enhances/replaces std::enable_shared_from_this. AMP has use cases that are not properly handled by enable_shared_from_this. Specifically some of the vectors in AMP are managed by external packages that do not use shared_ptr. AMP then requires a shared_ptr for some of its interfaces. This causes a problem because if we try to use shared_from_this() on a pointer that is not managed by the smart pointer, then the function crashes. An example of this occurs in PetscManagedVector where PETSc manages the vectors, but we want to enable the underlying data to be an AMP vector. This class provides the additional functionallity
