Method Detail

intToHexString

public static java.lang.String intToHexString(int number)

public static int hexStringToInt(java.lang.String s)
                          throws java.lang.NumberFormatException

Convert a hex String to an integer. Be careful of -1. Java IO is really bad!

Throws:

java.lang.NumberFormatException

longToHexString

public static java.lang.String longToHexString(long number)
                                        throws java.lang.NumberFormatException

                            throws java.lang.NumberFormatException

Convert a hex String to a long.

hostInetAddr

public static int hostInetAddr()
                        throws java.net.UnknownHostException

Returns:

an integer representing the ip address of the local machine. Essentially the bytes of the InetAddress are shuffled into the integer. This was once part of the Uid class but has been separated for general availability.

Throws:

java.net.UnknownHostException

Since:

JTS 2.1.

getpid

public static final int getpid()

Returns:

the process id. This had better be unique between processes on the same machine. If not we're in trouble!

Since:

JTS 2.1.

getProcessUid

public static final Uid getProcessUid()

Returns:

a Uid representing this process.

Since:

JTS 2.1.

isWindows

public static final boolean isWindows()

setProcess

public static final void setProcess(Process p)

getDefaultProcess

public static final Process getDefaultProcess()
