Motivation: There is no reason for `compose()` to be an instance method on `BufferAllocator` since the allocator implementation should not influence how this method is implemented. Modification: Make `compose()` a static method and move it to the `Buffer` interface. Also move its companion methods `extendComposite()` and `isComposite()` to the `Buffer` interface. Result: The composite buffer methods are now in a more sensible place. Also: decided _against_ making `extendComposite()` and `isComposite()` instance methods, because the subtle behaviours of `extendComposite()` means it would behave quite differently for non-composite buffers. Also: `isComposite()` is not an instance method because it relates to the hard-coded and concrete `CompositeBuffer` implementation. |
