IAllocator_Xfer

IAllocator_Xfer provides a type-erased interface to a specific native allocator implementation.

It supports runtime polymorphism for the cpp:class:xo::mm::AAllocator facet. Application code iis unlikely to directly interact with this class

Context

Each method operates by downcasting its first argument to the known target native interface type, and delegating to native interface method with the same name.

For example (paraphrasing):

template <typename DRepr, typename IAllocator_DRepr>
bool IAllocator_Xfer<DRepr, IAllocator_DRepr>::contains(Copaque d,
                                                        const void * p) const ...
{
  return IAllocator_DRepr::contains(*(DRepr*)(d), p);
};

Code for other methods follows the same pattern; in fact expect to be able to generate class definition mechanically at some point.

Application code will not normally interact with IAllocator_Xfer. It will be used once for each specific allocator implementation (e.g. with xo::mm::IAllocator_DArena). In any case, can include the transfer template with:

#include <xo/alloc2/IAllocator_Xfer.hpp>
