| 57 | * Generic DVD Driver.␊ |
| 58 | * @discussion␊ |
| 59 | * Storage drivers are split into two parts: the Generic Driver handles␊ |
| 60 | * all generic device issues, independent of the lower-level transport␊ |
| 61 | * mechanism (e.g. SCSI, ATA, USB, FireWire). All storage operations␊ |
| 62 | * at the Generic Driver level are translated into a series of generic␊ |
| 63 | * device operations. These operations are passed via the Device Nub␊ |
| 64 | * to a Transport Driver, which implements the appropriate␊ |
| 65 | * transport-dependent protocol to execute these operations.␊ |
| 66 | * ␊ |
| 67 | * To determine the write-protect state of a device (or media), for␊ |
| 68 | * example, the generic driver would issue a call to the␊ |
| 69 | * Transport Driver's reportWriteProtection method. If this were a SCSI␊ |
| 70 | * device, its Transport Driver would issue a Mode Sense command to␊ |
| 71 | * extract the write-protection status bit. The Transport Driver then␊ |
| 72 | * reports true or false to the generic driver.␊ |
| 73 | * ␊ |
| 74 | * The generic driver therefore has no knowledge of, or involvement␊ |
| 75 | * with, the actual commands and mechanisms used to communicate with␊ |
| 76 | * the device. It is expected that the generic driver will rarely, if␊ |
| 77 | * ever, need to be subclassed to handle device idiosyncrasies; rather,␊ |
| 78 | * the Transport Driver should be changed via overrides.␊ |
| 79 | * ␊ |
| 80 | * A generic driver could be subclassed to create a different type of␊ |
| 81 | * generic device. The generic driver IODVDBlockStorageDriver class is a subclass␊ |
| 82 | * of IOCDBlockStorageDriver, adding DVD functions. Similarly, the Transport Driver␊ |
| 83 | * IODVDBlockStorageDevice is a subclass of IOCDBlockStorageDevice, adding DVD ␊ |
| 84 | * functions.␊ |
