Detailed Description
template<typename SCALAR, unsigned int NDIM>
struct mpblocks::clarkson93::ExampleTraits2< SCALAR, NDIM >::SimplexMgr
template for allocators & memory managers
The triangulation doesn't support removal of points. Thus simplices are never deleted individually (rather, all at once when the triangulation is cleared). Thus we divert memory management to the user of the libary. The allocator is responsible for keeping track of every object it allocates an be delete them all when cleared
This example preallocates a fixed size array of storage for objects. When create() is called it takes the next unused pointers, calls in-place operator new() and then returns the pointer. When it is reset, it goes through the list of allocated pointers and calls the destructor (ptr)->~T() on each of them.
For the most part, Alloc<T> is only used to construct POD types so this is a bit of a moot point.
- Note
- : Alloc must be default constructable. It will be passed to setup.prepare( Alloc<T> ) so if you need to do any allocator initialization you must do it in Setup
