This method is defined if both allocators define it, and forwards to SmallAllocator or LargeAllocator appropriately.
This method is defined only if at least one of the allocators defines it, and work similarly to reallocate.
The memory is obtained from SmallAllocator if s <= threshold, or LargeAllocator otherwise.
Composite allocators involving nested instantiations of Segregator make it difficult to access individual sub-allocators stored within. allocatorForSize simplifies the task by supplying the allocator nested inside a Segregator that is responsible for a specific size s.
This function is defined only if both allocators define it, and forwards appropriately depending on b.length.
This function is defined only if both allocators define it, and calls deallocateAll for them in turn.
This function is defined only if both allocators define it, and returns the conjunction of empty calls for the two.
This method is defined only if at least one of the allocators defines it. If SmallAllocator defines expand and b.length + delta <= threshold, the call is forwarded to SmallAllocator. If LargeAllocator defines expand and b.length > threshold, the call is forwarded to LargeAllocator. Otherwise, the call returns false.
This method is defined only if both allocators define it. The call is forwarded to SmallAllocator if b.length <= threshold, or LargeAllocator otherwise.
This method is defined only if at least one of the allocators defines it. If SmallAllocator defines reallocate and b.length <= threshold && s <= threshold, the call is forwarded to SmallAllocator. If LargeAllocator defines expand and b.length > threshold && s > threshold, the call is forwarded to LargeAllocator. Otherwise, the call returns false.
This method is defined only if at least one of the allocators defines it. The good allocation size is obtained from SmallAllocator if s <= threshold, or LargeAllocator otherwise. (If one of the allocators does not define goodAllocSize, the default implementation in this module applies.)
The alignment offered is the minimum of the two allocators' alignment.
import stdx.allocator.building_blocks.free_list : FreeList; import stdx.allocator.gc_allocator : GCAllocator; import stdx.allocator.mallocator : Mallocator; alias A = Segregator!( 1024 * 4, Segregator!( 128, FreeList!(Mallocator, 0, 128), GCAllocator), Segregator!( 1024 * 1024, Mallocator, GCAllocator) ); A a; auto b = a.allocate(200); assert(b.length == 200); a.deallocate(b);
Dispatches allocations (and deallocations) between two allocators (SmallAllocator and LargeAllocator) depending on the size allocated, as follows. All allocations smaller than or equal to threshold will be dispatched to SmallAllocator. The others will go to LargeAllocator.
If both allocators are shared, the Segregator will also offer shared methods.
