Method Details

newInstance

public static Dot11SequenceControl 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 Dot11SequenceControl object.

Throws:

IllegalRawDataException - if parsing the raw data fails.

getFragmentNumber

public byte getFragmentNumber()

Returns:

fragmentNumber

getFragmentNumberAsInt

public int getFragmentNumberAsInt()

Returns:

fragmentNumber

getSequenceNumber

public short getSequenceNumber()

Returns:

sequenceNumber

getSequenceNumberAsInt

public int getSequenceNumberAsInt()

Returns:

sequenceNumber

getBuilder

public Dot11SequenceControl.Builder getBuilder()

Returns:

a new Builder object populated with this object's fields.

getRawData

public byte[] getRawData()

Returns:

the raw data.

length

public int length()

Returns:

length

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
