Method Detail

newInstance

public static RadiotapDataChannel 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 RadiotapChannel object.

Throws:

IllegalRawDataException - if parsing the raw data fails.
