Constructor Detail

Dot11ManagementHeader

protected Dot11ManagementHeader(byte[] rawData,
                                int offset,
                                int length)
                         throws IllegalRawDataException

Parameters:

rawData - rawData

offset - offset

length - length

Throws:

IllegalRawDataException - if parsing the raw data fails.

Dot11ManagementHeader

protected Dot11ManagementHeader(Dot11ManagementPacket.Builder builder)

Parameters:

builder - builder

Method Detail

getFrameControl

public Dot11FrameControl getFrameControl()

Returns:

frameControl

getDuration

public short getDuration()

Returns:

duration

getDurationAsInt

public int getDurationAsInt()

Returns:

duration

getAddress1

public MacAddress getAddress1()

Returns:

address1

getAddress2

public MacAddress getAddress2()

Returns:

address2

getAddress3

public MacAddress getAddress3()

Returns:

address3

getSequenceControl

public Dot11SequenceControl getSequenceControl()

Returns:

sequenceControl

getHtControl

public Dot11HtControl getHtControl()

Returns:

htControl. May be null.

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

getHeaderName

protected abstract java.lang.String getHeaderName()

Returns:

the header name.

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

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

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
