Detailed Description

template<typename T>
struct aff::util::SHeap< T >

A structure to be shared between different SharedHeap instances.

This is the core part of represented shared heap. Only objects of this class allocate and delete memory. The SharedHeap representation has holds a pointer to an instance of this struct. The representation is responsible for doing the reference counting by incrementing and decrementing Mnref and to call the destructor of SHeap once the reference count drops to zero. The actual deallocation of the memory block used for the array is, however, done within the destructor of SHeap.

For arrays taken from Fortran code we use a flag Mextern. If it is true, this indicates that memory should neither be allocated be the constructor nor given free by the destructor.
