Method Summary

abstract boolean	acceptPacket(ProtocolMessage packet) check whether the given packet belongs to this flow since we may have different standards (resolution) of flows, this is an abstract method here
void	dumpBinaryOut(java.io.DataOutputStream outStream) Dump the flow to a stream
abstract byte[]	dumpToBytes() Generate a byte array from this record.
abstract java.lang.Long	makeKey() construct a key for this flow that can be used as hash key.
void	readBinaryIn(java.io.DataInputStream inStream) read data from a binary stream
abstract void	readFromBytes(byte[] bytes, int len) extract the record information from a byte array
int	recordSize() recordSize the "next" field is NOT included when count the size of the record.
NetFlow	removeFlow(NetFlow flow) remove the give flow from the list with this flow as the head return the rest of the list

Method Detail

dumpToBytes

public abstract byte[] dumpToBytes()

Generate a byte array from this record.

readFromBytes

public abstract void readFromBytes(byte[] bytes,
                                   int len)

extract the record information from a byte array

Parameters:

bytes - the byte array that stores the data

len - the length of the data stored in the array (Not the length of the array)

dumpBinaryOut

public void dumpBinaryOut(java.io.DataOutputStream outStream)

Dump the flow to a stream

Parameters:

outStream - the outputStream into which the data is dumped.

readBinaryIn

public void readBinaryIn(java.io.DataInputStream inStream)

read data from a binary stream

makeKey

public abstract java.lang.Long makeKey()

construct a key for this flow that can be used as hash key.

removeFlow

public NetFlow removeFlow(NetFlow flow)

remove the give flow from the list with this flow as the head return the rest of the list

recordSize

public int recordSize()

recordSize the "next" field is NOT included when count the size of the record.

acceptPacket

public abstract boolean acceptPacket(ProtocolMessage packet)

check whether the given packet belongs to this flow since we may have different standards (resolution) of flows, this is an abstract method here

Parameters:

packet - the packet to be checked.

update

public abstract void update(ProtocolMessage packet,
                            float curTime)

update the flow for the given packet

Parameters:

packet - given packet

curTime - the current time
