delete_array()

template<class T >

virtual void AlignedVector< T >::Deleter::MPISharedMemDeleterAction::delete_array ( const AlignedVector< T > *  aligned_vector, T *  ptr  )

virtual

The function that implements the action of de-allocating memory. It receives as arguments a pointer to the owning AlignedVector object as well as a pointer to the memory being de-allocated.

Implements AlignedVector< T >::Deleter::DeleterActionBase.
