Maneuver.Builder

public Builder(int type)

Constructs a new instance of a Builder.

The type should be chosen to reflect the closest semantic meaning of the maneuver. In some cases, an exact type match is not possible, but choosing a similar or slightly more general type is preferred. Using TYPE_UNKNOWN is allowed, but some head units will not display any information in that case.

public @NonNull Maneuver build()

Constructs the Maneuver defined by this builder.

public @NonNull Maneuver.Builder setIcon(@NonNull CarIcon icon)

Sets an image representing the maneuver.

See CarIcon for more details related to providing icon and image resources that work with different car screen pixel densities.

public @NonNull Maneuver.Builder setRoundaboutExitAngle(
    @IntRange(from = 1, to = 360) int roundaboutExitAngle
)

Sets an exit angle for roundabout maneuvers.

Use for when type is TYPE_ROUNDABOUT_ENTER_AND_EXIT_CW_WITH_ANGLE or TYPE_ROUNDABOUT_ENTER_AND_EXIT_CCW_WITH_ANGLE. The roundaboutExitAngle represents the degrees traveled in circulation from the entrance to the exit.

For example, in a 4 exit example, if all the exits are equally spaced then exit 1 would be at 90 degrees, exit 2 at 180, exit 3 at 270 and exit 4 at 360. However if the exits are irregular then a different angle could be provided.

public @NonNull Maneuver.Builder setRoundaboutExitNumber(@IntRange(from = 1) int roundaboutExitNumber)

Sets an exit number for roundabout maneuvers.

Use for when type is TYPE_ROUNDABOUT_ENTER_AND_EXIT_CW, TYPE_ROUNDABOUT_ENTER_AND_EXIT_CCW, TYPE_ROUNDABOUT_ENTER_AND_EXIT_CW_WITH_ANGLE or TYPE_ROUNDABOUT_ENTER_AND_EXIT_CCW_WITH_ANGLE. The roundaboutExitNumber starts from 1 to designate the first exit after joining the roundabout, and increases in circulation order.

For example, if the driver is joining a counter-clockwise roundabout with 4 exits, then the exit to the right would be exit #1, the one straight ahead would be exit #2, the one to the left would be exit #3 and the one used by the driver to join the roundabout would be exit #4.
