SensorStorage()

Method Summary

Modifier and Type	Method and Description
void	clearSensorEvent() Clear the HashMap to keep SensorEvent objects.
java.util.ArrayList<SensorHolder>	getSensorHolders() Generate an ArrayList of SensorHolder objects as the latest collection of SensorEvent object and timestamp.
java.lang.String	getSensorTypeName(int sensorType) Each Sensor object has its own name such like "Goldfish 3-axis Accelerometer", but it's arbitrarily named by the device vendor and thus difficult to handle programmatically.
java.util.ArrayList<java.lang.String>	getSensorTypeNames(java.util.ArrayList<java.lang.Integer> sensorTypes) Generate an ArrayList of SensorTypeName which corresponds to the given ArrayList of SensorType.
java.util.ArrayList<java.lang.Integer>	getSensorTypes() Available Sensor objects on this device are kept in the internal HashMap, which uses the sensor type as the key.
android.hardware.Sensor	lookupSensor(int sensorType)
void	registerSensor(android.hardware.Sensor sensor)
void	setSensorEvent(android.hardware.SensorEvent sensorEvent, long unixTime) Keep the given SensorEvent object along with timestamp in the internal HashMap.

Method Detail

registerSensor

public void registerSensor(@NonNull
                           android.hardware.Sensor sensor)

lookupSensor

@Nullable
public android.hardware.Sensor lookupSensor(int sensorType)

getSensorTypes

@NonNull
public java.util.ArrayList<java.lang.Integer> getSensorTypes()

Available Sensor objects on this device are kept in the internal HashMap, which uses the sensor type as the key. This method returns the sorted list of hash keys (= sensor types).

Returns:

Sorted list of available sensor types

getSensorTypeName

@NonNull
public java.lang.String getSensorTypeName(int sensorType)

Each Sensor object has its own name such like "Goldfish 3-axis Accelerometer", but it's arbitrarily named by the device vendor and thus difficult to handle programmatically. Instead, we use symbolic name derived from sensor type definitions. For example, we take "accelerometer" from the constant value "android.sensor.accelerometer", defined as Sensor.STRING_TYPE_ACCELEROMETER.

Parameters:

sensorType - Target sensor type, which is a hash key

Returns:

Symbolic sensor type name such like "accelerometer"

getSensorTypeNames

@NonNull
public java.util.ArrayList<java.lang.String> getSensorTypeNames(@NonNull
                                                                         java.util.ArrayList<java.lang.Integer> sensorTypes)

Generate an ArrayList of SensorTypeName which corresponds to the given ArrayList of SensorType.

Parameters:

sensorTypes - ArrayList of target sensor types

Returns:

ArrayList of sensor type names

setSensorEvent

public void setSensorEvent(@NonNull
                           android.hardware.SensorEvent sensorEvent,
                           long unixTime)

Keep the given SensorEvent object along with timestamp in the internal HashMap.

Parameters:

sensorEvent - the SensorEvent object notified from system

unixTime - timestamp of the notification

getSensorHolders

public java.util.ArrayList<SensorHolder> getSensorHolders()

Generate an ArrayList of SensorHolder objects as the latest collection of SensorEvent object and timestamp.

Returns:

ArrayList of SensorHolder objects

clearSensorEvent

public void clearSensorEvent()

Clear the HashMap to keep SensorEvent objects.
