Detailed Description

A memory allocator (abstract base class) used by ss_m::sort_file and its adjuncts.

The ssm_sort::CSKF, ssm_sort::MOF and ssm_sort::UMOF callbacks may need to allocate memory, in which case they should use the factory passed in as an argument; this allows the storage manager to free the memory using the same allocator.

These allocators are used with object_t (record handles) and skey_t (key handles).

The default allocators used by ss_m::sort_file are

• factory_t::none : does not allocate or free, used for statically- allocated space.
• factory_t::cpp_vector : a factory that allocates byte-strings that start on a double-aligned boundary and frees them.

Users must write their own factories that inherit from factory_t.
