Method Details

getNextHeader

public IpNumber getNextHeader()

Returns:

nextHeader

getHdrExtLen

public byte getHdrExtLen()

Returns:

hdrExtLen

getHdrExtLenAsInt

public int getHdrExtLenAsInt()

Returns:

hdrExtLen

getRoutingType

public IpV6RoutingType getRoutingType()

Returns:

routingType

getSegmentsLeft

public byte getSegmentsLeft()

Returns:

segmentsLeft

getSegmentsLeftAsInt

public int getSegmentsLeftAsInt()

Returns:

segmentsLeft

getData

public IpV6ExtRoutingPacket.IpV6RoutingData getData()

Returns:

data

getRawFields

protected 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 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(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
