<allocators> macros
ALLOCATOR_DECL
Yields an allocator class template.
#define ALLOCATOR_DECL(cache, sync, name) <alloc_template>
Remarks
The macro yields a template definition template <class Type> class name {.....} and a specialization template <> class name<void> {.....} which together define an allocator class template that uses the synchronization filter sync and a cache of type cache.
For compilers that can compile rebind, the resulting template definition looks like this:
struct rebind
{ /* convert a name<Type> to a name<Other> */
typedef name<Other> other;
};
For compilers that cannot compile rebind the resulting template definition looks like this:
template <class Type<class name
: public stdext::allocators::allocator_base<Type,
sync<stdext::allocators::rts_alloc<cache>>>
{
public:
name() {}
template <class Other>
name(const name<Other>&) {}
template <class Other>
name& operator= (const name<Other>&)
{
return *this;
}
};
CACHE_CHUNKLIST
Yields stdext::allocators::cache_chunklist<sizeof(Type)>.
#define CACHE_CHUNKLIST <cache_class>
Remarks
CACHE_FREELIST
Yields stdext::allocators::cache_freelist<sizeof(Type), max>.
#define CACHE_FREELIST(max) <cache_class>
Remarks
CACHE_SUBALLOC
Yields stdext::allocators::cache_suballoc<sizeof(Type)>.
#define CACHE_SUBALLOC <cache_class>
Remarks
SYNC_DEFAULT
Yields a synchronization filter.
#define SYNC_DEFAULT <sync_template>
Remarks
If a compiler supports compiling both single-threaded and multi-threaded applications, for single-threaded applications the macro yields stdext::allocators::sync_none; in all other cases it yields stdext::allocators::sync_shared.
