| 31 | * Describes how a logical display is configured. |
| 32 | * <p> |
| 33 | * At this time, we only support logical displays that are coupled to a particular |
| 34 | * primary display device from which the logical display derives its basic properties |
| 35 | * such as its size, density and refresh rate. |
| 36 | * </p><p> |
| 37 | * A logical display may be mirrored onto multiple display devices in addition to its |
| 38 | * primary display device. Note that the contents of a logical display may not |
| 39 | * always be visible, even on its primary display device, such as in the case where |
| 40 | * the primary display device is currently mirroring content from a different |
| 41 | * logical display. |
| 42 | * </p><p> |
| 43 | * This object is designed to encapsulate as much of the policy of logical |
| 44 | * displays as possible. The idea is to make it easy to implement new kinds of |
| 45 | * logical displays mostly by making local changes to this class. |
| 46 | * </p><p> |
| 47 | * Note: The display manager architecture does not actually require logical displays |
| 48 | * to be associated with any individual display device. Logical displays and |
| 49 | * display devices are orthogonal concepts. Some mapping will exist between |
| 50 | * logical displays and display devices but it can be many-to-many and |
| 51 | * and some might have no relation at all. |
| 52 | * </p><p> |
| 53 | * Logical displays are guarded by the {@link DisplayManagerService.SyncRoot} lock. |
| 54 | * </p> |
