Interface DiskFactory

All Known Implementing Classes:
CpmDiskFactory, DosDiskFactory, GutenbergDiskFactory, NakedosDiskFactory, PascalDiskFactory, ProdosDiskFactory, RdosDiskFactory
public interface DiskFactory
The DiskFactory inspects a given Source inspect it to see if it matches filesystem structure(s). Invoke via Disks.inspect(Source) which will return a Context. The Context _can be empty_. If this is the case, devices can be created via the DiskFactory.Context.blockDevice() and DiskFactory.Context.trackSectorDevice() builders.
The builders follow the observation about what each filesystem currently uses:

  • 13-sector disks are only track/sector devices. (And RDOS has a unique mapping to 256 byte blocks).
  • 16-sector disks have a variety of sector mappings. It can also double as a "standard" 512 byte block, as well as a unique CP/M 1024 block device.
  • 800K disks are only standard 512 byte block (Prodos or Pascal). OzDOS and UniDOS do have unique mappings to track and sector, but logically, they are block devices.
  • Anything else (larger than 800K) are "hard-disk" images and only blocks.
