 | Signature | Type | Description |
 | --- | --- |--- |
+| linear_allocator<br/>\<Size\> | Raw | Allocates a block of `Size` which it then hands out in chunks, similar to `stack_allocator`.<br/>Simply increments a counter during allocation, making it faster than pre_allcoator, but it also rarely deallocates.<br/>Has a max allocation size of the `Size` given, but unlike the `stack_allocator` constructs it's memory dynamically. |
 | mallocator | Raw | An allocator which tries to align memory when allocating.<br/>Almost like std::allocator, except it has no type. |
 | pre_allocator<br/>\<Size\> | Raw | Uses a linked list to determine whether a given chunk of memory is free or allocated, which takes O(n) time.<br/>Has a max allocation size of the `Size` given. |
 | stack_allocator<br/>\<Size\> | Raw | Uses a preallocated `stack<Size>`, which has to be passed in during construction.<br/>Simply increments a counter during allocation, making it faster than pre_allcoator, but it also rarely deallocates.<br/>Has a max allocation size of the `Size` given. |
 | cascading_allocator<br/>\<Allocator\> | Composite | Attempts to allocate using the given allocator, but upon failure will create a new allocator and keep a reference to the old one.<br/>Deallocation can take O(n) time as it may have to traverse multiple allocator instances to find the right one. |
-| composite_allocator<br/>\<Primary, Fallback\> | Composite | Delegates allocation between 2 allocators.<br/>It first attempts to allocate with the `Primary` allocator, but upon failure will use the `Fallback` allocator. |
+| fallback_allocator<br/>\<Primary, Fallback\> | Composite | Delegates allocation between 2 allocators.<br/>It first attempts to allocate with the `Primary` allocator, but upon failure will use the `Fallback` allocator. |
 | overflow_allocator<br/>\<Allocator, std::ostream\> | Composite | Checks for memory corruption/leak when allocating/constructing via it's specified allocator. It streams the results to the std::ostream specified. |
 | segragator_allocator<br/>\<Threshold, Primary, Fallback\> | Composite | Delegates allocation between 2 allocators based on a size threshold. |
 | type_allocator<br/>\<T, Allocator\> | Composite | Wraps around the specified allocator with a type. This can be used to make the other allocators STL compliant, so they can be used with STL containers. |

 | --- | --- |
-| void* allocate(size_type size) | Attempts to allocate a chunk of memory defined by `size`. |
+| void* allocate(size_type size) | Attempts to allocate a chunk of memory defined by `size`. For non-typed allocators the size is in bytes, but for typed allocators it's the amount of objects of the given type. |
 | void deallocate(void* ptr, size_type size) | Attempts to deallocate the memory at location `ptr` with the given size, `size`. |
 | void construct(T* ptr, Args&& args) | Calls the constructor of a specific type at the location `ptr` with `args`.<br/>Not all allocators define this method. |
 | void destroy(T* ptr) | Calls the destructor of a specific type at the location `ptr`.<br/>Not all allocators define this method. |
