Field Detail

TIMEOUT

public static final int TIMEOUT

Deprecated.

How long to wait before giving up on a command (milliseconds).

Constructor Detail

Command

public Command(String[] argsArray)
        throws IOException,
               InterruptedException

Deprecated.

Create command and start it running.

Command

public Command(Vector argsVector)
        throws IOException,
               InterruptedException

Deprecated.

Method Detail

println

public void println(String line)

Deprecated.

Send a line of text to the command's input stream.

waitFor

public boolean waitFor(long timeoutInMillis)
                throws InterruptedException,
                       IOException

Deprecated.

Wait for the command to finish. Note: the Sun JDK sends a end-of-file to stdin but jview does not, so the process needs to explicitly be told to exit.

Returns:

true if the process has exited. (False means the process is hung.)

getArgs

public String[] getArgs()

Deprecated.

Get arguments used to start the command

getOutput

public String getOutput()

Deprecated.

Get stdout from the command.

getErrorOutput

public String getErrorOutput()

Deprecated.

Get stderr from the command.

getExitValue

public int getExitValue()

Deprecated.

Get the command's exit value.

dumpResult

public void dumpResult(PrintWriter out)

Deprecated.

Print the results of the command to an output stream (for debugging).

run

public void run()

Deprecated.

Specified by:

run in interface Runnable

isWindows

public static boolean isWindows()

Deprecated.

isMacintosh

public static boolean isMacintosh()

Deprecated.

isOS2

public static boolean isOS2()

Deprecated.

getMACAddress

public static String getMACAddress()

Deprecated.

Retrieves the MAC Address (Hardware address) from the system. If multiple NIC cards are present, there is no guarantee as to which address will be returned. This method works (in most cases) on Windows, Solaris, HPUX, LINUX, and AIX assuming some standard commands are available at the command line. The commands required are as follows:

- Windows: "ipconfig /all"
- Solaris: "/usr/sbin/arp ip_address"
- HPUX: "/usr/sbin/lanscan -a"
- LINUX: "/sbin/ifconfig"
- AIX: "/bin/entstat en0"
For AIX, it is also assumed that a NIC card exists at /dev/en0.

getIPAddress

public static String getIPAddress()

Deprecated.

helper to retrieve the systems IP Address

main

public static void main(String[] args)

Deprecated.
