ScanResult

public class ScanResult
extends Object implements Parcelable

java.lang.Object
   ↳ android.net.wifi.ScanResult


Describes information about a detected access point. In addition to the attributes described here, the supplicant keeps track of quality, noise, and maxbitrate attributes, but does not currently report them to external clients.

Public methods

is80211mcResponder

Added in API level 23
boolean is80211mcResponder ()

Returns
boolean

isPasspointNetwork

Added in API level 23
boolean isPasspointNetwork ()

Returns
boolean

toString

Added in API level 1
String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Returns
String a string representation of the object.

Hooray!
