Method Details

calcChecksum
private short calcChecksum(Inet6Address srcAddr, Inet6Address dstAddr, byte[] header, byte[] payload) -
getType
- Returns:
- type
-
getCode
- Returns:
- code
-
getChecksum
public short getChecksum()- Returns:
- checksum
-
getRawFields
Description copied from class:AbstractPacket.AbstractHeaderReturns a list of byte arrays which represents this header's fields. This method is called bycalcLength()andbuildRawData().- Specified by:
getRawFieldsin classAbstractPacket.AbstractHeader- Returns:
- a list of byte arrays which represents this header's fields
-
getRawFields
-
buildRawData
private byte[] buildRawData(boolean zeroInsteadOfChecksum) -
length
public int length()Description copied from class:AbstractPacket.AbstractHeaderReturns the header length in bytes. This method callscalcLength()and caches the return value when it is called for the first time, and then, this method returns the cached value from the second time.- Specified by:
lengthin interfacePacket.Header- Overrides:
lengthin classAbstractPacket.AbstractHeader- Returns:
- the length of the byte stream of the header represented by this object in bytes
-
buildString
Description copied from class:AbstractPacket.AbstractHeaderThis method builds the valuetoString()will return.- Overrides:
buildStringin classAbstractPacket.AbstractHeader- Returns:
- a string representation of this object
-
equals
Description copied from class:AbstractPacket.AbstractHeaderIndicates whether some other object is "equal to" this one using return values ofgetRawData(). This method should be overridden so that it does more strict comparisons more efficiently.- Overrides:
equalsin classAbstractPacket.AbstractHeader
-
calcHashCode
protected int calcHashCode()Description copied from class:AbstractPacket.AbstractHeaderThis method builds the valuehashCode()will return using the byte arraygetRawData()returns. This method may be better to be overridden for performance reason.- Overrides:
calcHashCodein classAbstractPacket.AbstractHeader- Returns:
- a calculated hash code value for the object
-
