class Geo::GeoAllocationPage
A storage unit for a page based allocation system.
Despite looking like a std::allocator, you cannot fully implement an allocator using this kind of class alone (as allocators do not have state, and clearly, a page has state). As a result, this class is used by the GeoFixedPoolAllocator class, which is a std::allocator.

This class knows nothing of the types of object that it may be storing, it is just raw memory. Hence no constructors or destructors are called, that is the responsibility of the allocator. |
