Fields
Public methods
getAccess
public int getAccess ()
Returns the access type of the car property.
The access type could be one of the following:
CarPropertyConfig#VEHICLE_PROPERTY_ACCESS_NONECarPropertyConfig#VEHICLE_PROPERTY_ACCESS_READCarPropertyConfig#VEHICLE_PROPERTY_ACCESS_WRITECarPropertyConfig#VEHICLE_PROPERTY_ACCESS_READ_WRITE
| Returns | |
|---|---|
int |
the access type of the car property.
Value is VEHICLE_PROPERTY_ACCESS_NONE, VEHICLE_PROPERTY_ACCESS_READ, VEHICLE_PROPERTY_ACCESS_WRITE, or VEHICLE_PROPERTY_ACCESS_READ_WRITE |
getAreaIdConfig
public AreaIdConfig<T> getAreaIdConfig (int areaId)
Returns the AreaIdConfig for the specified areaId.
| Parameters | |
|---|---|
areaId |
int |
| Returns | |
|---|---|
AreaIdConfig<T> |
AreaIdConfig instance for passed areaId |
| Throws | |
|---|---|
IllegalArgumentException |
if areaId is not supported for property |
getAreaIdConfigs
public List<AreaIdConfig<T>> getAreaIdConfigs ()
Returns a list of AreaIdConfig for this property.
| Returns | |
|---|---|
List<AreaIdConfig<T>> |
list of AreaIdConfig instances for this property. |
getAreaIds
public int[] getAreaIds ()
Returns a list of area IDs supported for the vehicle property.
An area represents a unique element of a VehicleAreaType. For instance, if the
VehicleAreaType is VehicleAreaType#VEHICLE_AREA_TYPE_SEAT, then an example
area is VehicleAreaSeat.SEAT_ROW_1_LEFT.
An area ID is a combination of one or more areas, and is created by bitwise "OR"ing the
areas together. Areas from different VehicleAreaType values will not be mixed in a
single area ID. For example, a VehicleAreaWheel area cannot be combined
with a VehicleAreaSeat area in an area ID.
For properties that return VehicleAreaType#VEHICLE_AREA_TYPE_GLOBAL for getAreaType(), they only support a single area ID of 0.
Rules for mapping a non VehicleAreaType#VEHICLE_AREA_TYPE_GLOBAL property to area
IDs:
- A property is mapped to a set of area IDs that are impacted when the property value changes.
- An area cannot be part of multiple area IDs, it will only be part of a single area ID.
- When the property value changes in one of the areas in an area ID, then it will automatically change in all other areas in the area ID.
- The property value will be independently controllable in any two different area IDs.
| Returns | |
|---|---|
int[] |
the array of supported area IDs. |
getAreaType
public int getAreaType ()
Returns the area type of the car property.
The area type could be one of the following:

| Returns | |
|---|---|
int |
the area type of the car property.
Value is VehicleAreaType.VEHICLE_AREA_TYPE_GLOBAL, VehicleAreaType.VEHICLE_AREA_TYPE_WINDOW, VehicleAreaType.VEHICLE_AREA_TYPE_SEAT, VehicleAreaType.VEHICLE_AREA_TYPE_DOOR, VehicleAreaType.VEHICLE_AREA_TYPE_MIRROR, or VehicleAreaType.VEHICLE_AREA_TYPE_WHEEL |
getChangeMode
public int getChangeMode ()
