Method Detail
-
newPacket
public static UdpPacket newPacket(byte[] rawData, int offset, int length) throws IllegalRawDataException
A static factory method. This method validates the arguments byByteArrays.validateBounds(byte[], int, int)
, which may throw exceptions undocumented here.- Parameters:
rawData
- rawDataoffset
- offsetlength
- length- Returns:
- a new UdpPacket object.
- Throws:
IllegalRawDataException
- if parsing the raw data fails.
-
getHeader
public UdpPacket.UdpHeader 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 interfacePacket
- Specified by:
getHeader
in interfaceTransportPacket
- Overrides:
getHeader
in classAbstractPacket
- Returns:
- the Header object representing this packet's header. May be null if the header doesn't exist
-
getPayload
public Packet getPayload()
Description copied from class:AbstractPacket
Returns the Packet object representing this packet's payload. This subclass have to override this method if the packet represented by the subclass has a payload.- Specified by:
getPayload
in interfacePacket
- Overrides:
getPayload
in classAbstractPacket
- Returns:
- the Packet object representing this packet's payload. May be null if the payload doesn't exist
-
hasValidChecksum
public boolean hasValidChecksum(java.net.InetAddress srcAddr, java.net.InetAddress dstAddr, boolean acceptZero)
checksum verification is necessary for IPv6(i.e. acceptZero must be false)- Parameters:
srcAddr
- srcAddrdstAddr
- dstAddracceptZero
- acceptZero- Returns:
- true if the packet represented by this object has a valid checksum; false otherwise.
-
getBuilder
public UdpPacket.Builder getBuilder()
Description copied from interface:Packet
Returns a new Builder object populated with this object's fields' values.- Specified by:
getBuilder
in interfacePacket
- Specified by:

in classAbstractPacket
- Returns:
- a new Builder object populated with this object's fields values
