getPropertyId
public int getPropertyId ()

int |
Status of CarPropertyValue
Value is STATUS_AVAILABLE, STATUS_UNAVAILABLE, or STATUS_ERROR |
getTimestamp
public long getTimestamp ()
Returns the timestamp in nanoseconds at which the CarPropertyValue happened. For a
given car property, each new CarPropertyValue should be monotonically increasing
using the same time base as SystemClock.elapsedRealtimeNanos().
NOTE: Timestamp should be synchronized with other signals from the platform (e.g.
Location and SensorEvent instances).
Ideally, timestamp synchronization error should be below 1 millisecond.
| Returns | |
|---|---|
long |
|
getValue
public T getValue ()
Returns the value for CarPropertyValue.
Note:Caller must check the value of getStatus(). Only use
getValue() when getStatus() is STATUS_AVAILABLE. If not,
getValue() is meaningless.
| Returns | |
|---|---|
T |
|
hashCode
