Method Details

newInstance

public static Dot11LinkAdaptationControl newInstance(byte[] rawData,
 int offset,
 int length)
                                              throws IllegalRawDataException

A static factory method. This method validates the arguments by ByteArrays.validateBounds(byte[], int, int), which may throw exceptions undocumented here.

Parameters:

rawData - rawData

offset - offset

length - length

Returns:

a new Dot11LinkAdaptationControl object.

Throws:

IllegalRawDataException - if parsing the raw data fails.

isVhtMfb

public boolean isVhtMfb()

Returns:

true if the VHT_MFB field is set to 1; false otherwise.

isTrq

public boolean isTrq()

Returns:

true if the TRQ field is set to 1; false otherwise.

isAselIndicated

public boolean isAselIndicated()

Returns:

true if the MAI field is set to 14 (ASELI); false otherwise.
