extends AbstractPacket.AbstractHeader

Radiotap Header + Extended presence masks + Radiotap fields

 struct ieee80211_radiotap_header {
         u_int8_t        it_version; // currently, this is always 0
         u_int8_t        it_pad;     // currently unused, just for for the alignment
         u_int16_t       it_len;     // entire length
         u_int32_t       it_present; // presence mask

Method Detail

getVersion

public byte getVersion()

Returns:

version

getVersionAsInt

public int getVersionAsInt()

Returns:

version

getPad

public byte getPad()

Returns:

pad

getLength

public short getLength()

Returns:

length

getLengthAsInt

public int getLengthAsInt()

Returns:

length

getPresentBitmasks

public java.util.ArrayList<RadiotapPresentBitmask> getPresentBitmasks()

Returns:

presentBitmasks

getDataFields

public java.util.ArrayList<RadiotapPacket.RadiotapData> getDataFields()

Returns:

dataFields

getRawFields

protected java.util.List<byte[]> getRawFields()

Description copied from class: AbstractPacket.AbstractHeader

Returns a list of byte arrays which represents this header's fields. This method is called by calcLength() and buildRawData().

Specified by:

getRawFields in class AbstractPacket.AbstractHeader

Returns:

a list of byte arrays which represents this header's fields

calcLength

public int calcLength()

Description copied from class: AbstractPacket.AbstractHeader

This method calculates the value length() will return by adding up the lengths of byte arrays in the list getRawFields() returns.

Overrides:

calcLength in class AbstractPacket.AbstractHeader

Returns:

a calculated length

buildString

protected java.lang.String buildString()

Description copied from class: AbstractPacket.AbstractHeader

This method builds the value toString() will return.

Overrides:

buildString in class AbstractPacket.AbstractHeader

Returns:

a string representation of this object

equals

public boolean equals(java.lang.Object obj)

Description copied from class: AbstractPacket.AbstractHeader

Indicates whether some other object is "equal to" this one using return values of getRawData(). This method should be overridden so that it does more strict comparisons more efficiently.

Overrides:

equals in class AbstractPacket.AbstractHeader

calcHashCode

protected int calcHashCode()

Description copied from class: AbstractPacket.AbstractHeader

This method builds the value hashCode() will return using the byte array getRawData() returns. This method may be better to be overridden for performance reason.

Overrides:

calcHashCode in class AbstractPacket.AbstractHeader

Returns:

a calculated hash code value for the object
