Class RadiotapDataAntennaNoise

java.lang.Object

org.pcap4j.packet.RadiotapDataAntennaNoise

All Implemented Interfaces:

Serializable, RadiotapPacket.RadiotapData

public final class RadiotapDataAntennaNoise
extends Object
implements RadiotapPacket.RadiotapData

Radiotap Antenna noise field. RF noise power at the antenna. This field contains a single signed 8-bit value, which indicates the RF signal power at the antenna, in decibels difference from 1mW.

Method Details

newInstance

public static RadiotapDataAntennaNoise 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 RadiotapAntennaNoise object.

Throws:

IllegalRawDataException - if parsing the raw data fails.
