Class TrackSectorToBlockAdapter

java.lang.Object
org.applecommander.device.TrackSectorToBlockAdapter
All Implemented Interfaces:
CapabilityProvider, BlockDevice, Device, HintProvider, Container, InformationProvider
public class TrackSectorToBlockAdapter extends Object implements BlockDevice
Provides a _very simple_ mapping from Track/Sectors to blocks. All sector skewing is expected to be handled in the TrackSectorDevice. As such, this device expects to map sectors in the given ("natural") order. (That is, ProDOS blocks are sectors 0,1 and 2,3 and 3,4 etc. RDOS is in physical order. CP/M is in CP/M's expected order.)

      public DataBuffer readBlock(int block)
      Description copied from interface: BlockDevice
      Read a single block from the disk.
      Specified by:

    • writeBlock

      public void writeBlock(int block, DataBuffer blockData)

      Write a single block to the disk.
      Specified by:

    • information

      public List<InformationGroup> information()
      Specified by:
      information in interface InformationProvider

    • format

      public void format()
      Description copied from interface: BlockDevice

      Format a disk. For most disks, this is simply a wipe to all zeros. If this disk has extended format (such as nibble formats), this is the opportunity to write out that format.

      NOTE: Adapter type devices have to be cautious about what device is responsible about formatting. For example, a UniDOS disk is 2x400K volumes on an 800K block device -- if they defer formatting to the 800K block device, a format on one volume also wipes out the other (in this case, do not defer to the "parent"). However, if the block adapter contains a nibble-based TrackSectorDevice, the actual formatting needs to get to the nibble device so it can lay down sector markers and the rest of the track structure.

      Specified by:
      format in interface BlockDevice
