Class SequentialAllocator

java.lang.Object
org.applecommander.os.SequentialAllocator
public class SequentialAllocator extends Object

The SequentialAllocator is intended to handle what is, essentially, a single dimension allocation. That is, if the disk is allocated by sequential chunks, this allocator should support it. For images that use T/S geometry instead of block geometry, the T/S will need to be transformed.

For instance, GameDOS allocates by T/S but allocates all in a chunk. So once there is a starting place, the rest of the file follows in a very specific order.
