CREATOR

Added in API level 36
public static final Creator<RangingData> CREATOR

Public methods

describeContents

Added in API level 36
public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.
Value is either 0 or

equals

Added in API level 36
public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
o Object: the reference object with which to compare.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

getAzimuth

Added in API level 36
public RangingMeasurement getAzimuth ()

Returns the azimuth measurement, or null if not available.

Returns
RangingMeasurement The RangingMeasurement representing the azimuth, or null.

getDistance

Added in API level 36
public RangingMeasurement getDistance ()

Returns the distance measurement.

Returns
RangingMeasurement The RangingMeasurement representing the distance.
This value may be null.

getDistanceStandardDeviationMeters

Added in version 36.1
public double getDistanceStandardDeviationMeters ()

Get the standard deviation of distance in meters .

Returned value will be positive if it exists

Returns
double The standard deviation of distance in meters.

Throws
IllegalStateException if distance standard deviation is not set.

getElevation

Added in API level 36
public RangingMeasurement getElevation ()

Returns the elevation measurement, or null if not available.

Returns
RangingMeasurement The RangingMeasurement representing the elevation, or null.

getRangingTechnology

Added in API level 36
public int getRangingTechnology ()

Returns the ranging technology used.

Returns
int The ranging technology as an integer.
Value is one of the following:

getRssi

Added in API level 36
public int getRssi ()

Returns the RSSI (Received Signal Strength Indicator) value.

Returns
int The RSSI value as an integer.

Throws
IllegalStateException if rssi is not set.

getTimestampMillis

Added in API level 36
public long getTimestampMillis ()

Returns the timestamp of when the ranging data was collected.
Value is a non-negative timestamp in the SystemClock.elapsedRealtime() time base.

Returns
long The timestamp in milliseconds.
Value is a non-negative timestamp in the SystemClock.elapsedRealtime() time base.

hasDistanceStandardDeviation

Added in version 36.1
public boolean hasDistanceStandardDeviation ()

Check if the standard deviation of distance is set.

Returns
boolean True if a standard deviation value is set, false if it isn't.

hasRssi

Added in API level 36
public boolean hasRssi ()

Returns whether an RSSI measurement is included with the data.

Returns
boolean The RSSI value as an integer.

hashCode

Added in API level 36
public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns
int a hash code value for this object.

toString

Added in API level 36
public String toString ()

Returns a string representation of the object.

Returns
String a string representation of the object.

writeToParcel

Added in API level 36
public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest Parcel: This value cannot be null.

flags int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE.
Value is either 0 or a combination of the following:
