header - header

Method Detail

getHeader

public abstract Dot11ManagementPacket.Dot11ManagementHeader getHeader()

Description copied from class: AbstractPacket

Returns the Header object representing this packet's header. This subclass have to override this method if the packet represented by the subclass has a header.

Specified by:

getHeader in interface Packet

Overrides:

getHeader in class AbstractPacket

Returns:

the Header object representing this packet's header. May be null if the header doesn't exist

getFcs

public java.lang.Integer getFcs()

Returns:

fcs. May be null.

calcLength

protected int calcLength()

Description copied from class: AbstractPacket

This method calculates the value length() will return by adding up the header length and the payload length. If you write this subclass which represents a packet with extra parts (e.g. a trailer), you need to override this method.

Overrides:

calcLength in class AbstractPacket

Returns:

a calculated length

buildRawData

protected byte[] buildRawData()

Description copied from class: AbstractPacket

This method builds the value getRawData() will return by concatenating the header's raw data and the payload's raw data. If you write this subclass which represents a packet with extra parts (e.g. a trailer), you need to override this method.

Overrides:

buildRawData in class AbstractPacket

Returns:

a raw data built

buildString

protected java.lang.String buildString()

Description copied from class: AbstractPacket

This method builds the value toString() will return by concatenating the header's string representation and the payload's string representation. If you write this subclass which represents a packet with extra parts (e.g. a trailer), you need to override this method.

Overrides:

buildString in class AbstractPacket

Returns:

a string representation of this object

getBuilder

public abstract Dot11ManagementPacket.Builder getBuilder()

Description copied from interface: Packet

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

Specified by:

getBuilder in interface Packet

Specified by:

getBuilder in class AbstractPacket

Returns:

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

hasValidFcs

public boolean hasValidFcs()

Returns:

true if this FCS is present and valid; false otherwise.
