Method Detail

ipArrToInt

public static int ipArrToInt(int[] ip)
                      throws java.lang.Exception

Converts an int[4] to an integer.

Parameters:

ip -

Returns:

the integer representation of the ip

Throws:

java.lang.Exception

ipArrToStructIP

public static structIP ipArrToStructIP(int[] ip)
                                throws java.lang.Exception

Converts an int[4] to a structIP

Parameters:

ip -

Returns:

the structIP representation of the ip

Throws:

java.lang.Exception

structIPtoIPArr

public static int[] structIPtoIPArr(structIP ip)

Converts a structIP to an int[4]

Parameters:

ip -

Returns:

the int[4] representation of the ip

structIPtoString

public static java.lang.String structIPtoString(structIP ip)

Converts a structIP to a String e.g. "1.2.3.4"

Parameters:

ip -

Returns:

the String representation of the ip

ipArrtoString

public static java.lang.String ipArrtoString(int[] ipArr)

Converts an int[4] to a String e.g. "1.2.3.4"

Parameters:

ipArr -

Returns:

the String representation of the ip

stringToIPArr

public static int[] stringToIPArr(java.lang.String ip)
                           throws java.lang.Exception

Converts a String e.g. "1.2.3.4" to an int[4]

Parameters:

ip -

Returns:

the int[4] representation of the ip

Throws:

java.lang.Exception - - if the it was not possible to parse the ip from the String

byteIPArrToIntIPArr

public static int[] byteIPArrToIntIPArr(byte[] ip)
                                 throws java.lang.Exception

Converts a byte[4] to an int[4]. Note that java uses signed bytes and therefore they first must be converted to positive numbers.

Parameters:

ip -

Returns:

the int[4] representation of the ip

Throws:

java.lang.Exception

colorToDouble

public static double colorToDouble(java.awt.Color c)
                            throws java.lang.Exception

Converts a Color to its double value although an int representation would be enough (RGB).

Parameters:

c -

Returns:

the double representation of the given Color

Throws:

java.lang.Exception

bpsToString

public static java.lang.String bpsToString(double bps)

taken from avgBW.c

Parameters:

bps - - float representing a value in bits per second

Returns:

String representation in bit/s, kbit/s, Mbit/s or Gbit/s

stringToBps

public static double stringToBps(java.lang.String s)

taken from avgBW.c

Parameters:

s - - String representing a value in bit/s, kbit/s, Mbit/s or Gbit/s

Returns:

float representing a value in bits per second

scpStringToBps

public static double scpStringToBps(java.lang.String s)

used for scp-output

Parameters:

s - - String representing a value in Byte/s, KByte/s, MByte/s or GByte/s 2009-01-10 LEO: corrected, because scp measures in Byte/s and NOT in bit/s

Returns:

float representing a value in bits per second

proxiesToStructIPs

public static structIP[] proxiesToStructIPs(java.util.Vector<X2XProxy> proxies)

gets an structIP-array consisting of the IPs of the proxies

Parameters:

proxies -

Returns:

proxy-ips

vectorStructBwInfoToBeanVector

public static java.util.Hashtable<X2XProxy,java.util.Vector<structBandwidthInfo>> vectorStructBwInfoToBeanVector(java.util.Hashtable<X2XProxy,java.util.Vector<StructBandwidthInfoBean>> loadedBwsPerNode)

Converts the vector with structBandwidthInfo elements to a vector with structBandwidthInfoBean elements.

Parameters:

loadedBwsPerNode -

Returns:

the converted loaded bws per node
