Detailed Description

The Instance template is used to extend normal classes with a pool based memory management.

It provides a framework of functions which allow the kernel to efficiently create or delete nodes. Also functions for getting information about the allocated/used memory are included. For example the function allocate in an arbitrary template class can be written as

template<typename ElementT>
inline Node* GenericModel<ElementT>::allocate(void)
{
  Node *n=new Instance<ElementT>;
  assert(n !=NULL);
  return n;
}

to take advantage of the pool based allocator. Likewise the function reserve_additional() looks like

template< typename ElementT>
inline void GenericModel<ElementT>::reserve_additional(size_t s)
{
  Instance<ElementT>::reserve_additional(s);
}

Note

Probably the best way to see how Instance is used is to look into the code where it is used. One Place for this is GenericModel-Template
