MIRROR_Y_POS
What it is
Mirror Y Position
The maxInt32Value and minInt32Value in VehicleAreaConfig must be defined. All integers between minInt32Value and maxInt32Value must be supported.
The minInt32Value indicates the mirror is tilted completely to the left. This must be a non-positive value. The maxInt32Value indicates the mirror is tilted completely to the right. This must be a non-negative value. 0 indicates the mirror is not tilted in either direction.
Values in between minInt32Value and maxInt32Value indicate a transition state between the left extreme and right extreme positions.
This property is not in any particular unit but in a specified range of relative positions.
This property is defined as VehiclePropertyAccess.READ_WRITE, but OEMs have the option to implement it as VehiclePropertyAccess.READ only.
How the ID is built
A property ID is a 32-bit value packing four fields. Reading 0x14400b42 apart:
| Field | Mask | Value | Means |
|---|---|---|---|
| Group | 0xf0000000 | 0x10000000 | SYSTEM |
| Area | 0x0f000000 | 0x04000000 | MIRROR |
| Type | 0x00ff0000 | 0x00400000 | INT32 |
| Ordinal | 0x0000ffff | 0x00000b42 | 0xb42 |
Reading it from an app
CarPropertyManager mgr = (CarPropertyManager)
car.getCarManager(Car.PROPERTY_SERVICE);
int value =
mgr.getIntProperty(VehiclePropertyIds.MIRROR_Y_POS, areaId);This property can be read and written, though an OEM may implement it as read-only. It fires a callback whenever the value changes.
