Public constructors

ScanResult

public ScanResult (ScanResult source)

copy constructor

Parameters
`source`	`ScanResult`: This value cannot be `null`.

ScanResult

public ScanResult ()

Construct an empty scan result.

Public methods

getInformationElements

public List<ScanResult.InformationElement> getInformationElements ()

Get all information elements found in the beacon.

Returns
`List<ScanResult.InformationElement>`	This value cannot be `null`.

getWifiStandard

public int getWifiStandard ()

return the AP wifi standard.

Returns
`int`	Value is `WIFI_STANDARD_UNKNOWN`, `WIFI_STANDARD_LEGACY`, `WIFI_STANDARD_11N`, `WIFI_STANDARD_11AC`, or `WIFI_STANDARD_11AX`

is80211mcResponder

public boolean is80211mcResponder ()

Returns
`boolean`

isPasspointNetwork

public boolean isPasspointNetwork ()

Returns
`boolean`

toString

public 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.
