RangingRequest

---

Kotlin |Java

public final class RangingRequest
extends Object implements Parcelable

java.lang.Object
↳	android.net.wifi.rtt.RangingRequest

---

Defines the ranging request to other devices. The ranging request is built using RangingRequest.Builder. A ranging request is executed using WifiRttManager#startRanging(RangingRequest, java.util.concurrent.Executor, RangingResultCallback).

The ranging request is a batch request - specifying a set of devices (specified using RangingRequest.Builder#addAccessPoint(ScanResult) and RangingRequest.Builder#addAccessPoints(List)).

Summary

Nested classes
class	RangingRequest.Builder Builder class used to construct RangingRequest objects.

From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor.

Fields

CREATOR

Added in API level 28

public static final Creator<RangingRequest> CREATOR

Public methods

describeContents

Added in API level 28

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 CONTENTS_FILE_DESCRIPTOR

equals

Added in API level 28

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: This value may be null.

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

getDefaultRttBurstSize

Added in API level 31

public static int getDefaultRttBurstSize ()

Returns the default RTT burst size used to determine the average range.

Returns
int	the RTT burst size used by default

getMaxPeers

Added in API level 28

public static int getMaxPeers ()

Returns the maximum number of peers to range which can be specified in a single RangingRequest. The limit applies no matter how the peers are added to the request, e.g. through RangingRequest.Builder#addAccessPoint(ScanResult) or RangingRequest.Builder#addAccessPoints(List).

Returns
int	Maximum number of peers.

getMaxRttBurstSize

Added in API level 31

public static int getMaxRttBurstSize ()

Returns the minimum RTT burst size that can be used to determine a average range.

Returns
int	the maximum RTT burst size that can be used

getMinRttBurstSize

Added in API level 31

public static int getMinRttBurstSize ()

Returns the minimum RTT burst size that can be used to determine a average range.

Returns
int	the minimum RTT burst size that can be used

getRttBurstSize

Added in API level 31

public int getRttBurstSize ()

Returns the RTT burst size used to determine the average range.

Returns
int	the RTT burst size used

hashCode

Added in API level 28

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.

writeToParcel

Added in API level 28

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest	Parcel: The Parcel in which the object should be written. 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 Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
