Merged slab allocator (allocators for objects of the same size are merged together).
| Type | The type of the objects to manage. |
| Slab_size | The size of a slab. |
| Max_free | The maximum number of free slabs. |
| Alloc | The allocator for the slabs. |
This slab allocator class is useful for merging slab allocators with the same parameters (equal sizeof(Type), Slab_size, Max_free, and Alloc parameters) together and share the overhead for the slab caches among all equal-sized objects.
