| Inner Class :static class ProcessMonitor extends Thread | |
| Method Summary | |
| final public static void | copyFile(String f1, String f2)
| | final public static String[] | exec(String[] cmd, String[] env, File f, long waitPeriod)
execute a given command. | | final public static String | getArgument(String[] args, int idx, String defaultValue)
| | final public static String[] | getFileList(String directory, String regex)
| | final public static void | getFileList(List filelist, String directory, String includesRegex, String excludesRegex, boolean recursive)
| | final public static byte[] | getLocalhostIP()
hopefully this will return the 'real' IP address even if the hosts file is configured
incorrectly (as I discovered on my test machine... | | final public static Method | getSetterMethod(Class c, String property, Class[] paramTypes)
| | final public static Object | invoke(Object obj, String method, Object[] args)
| | final public static void | invokeMain(Class c, String[] args)
| | final public static void | sleep(long time)
|
| exec | | final public static String[] exec(String[] cmd, String[] env, File f, long waitPeriod) throws IOException, InterruptedException(Code) | | execute a given command. This essentially wraps the command with a monitor so we can
kill it after a certain period of time. At the moment this is useful for Jikes, since it
seems to hang after certain errors, with no meaningful syserr output
Parameters:
cmd - the command array
Parameters:
env - the environment array
Parameters:
f - the file to use during the exec (@see java.lang.Runtime#getRuntime)
Parameters:
waitPeriod - the length of time to wait until we assume something has gone wrong and kill the process |
| getArgument | | final public static String getArgument(String[] args, int idx, String defaultValue)(Code) | | taking an array of arguments (usually in the main() method) return the value at
a particular index -- or if it is null/empty, return a default value
|
| getFileList | | final public static String[] getFileList(String directory, String regex)(Code) | | get a list of files matching a regex
|
| getFileList | | final public static void getFileList(List filelist, String directory, String includesRegex, String excludesRegex, boolean recursive)(Code) | | loads the specified list with File objects (recursing through directories if required)
|
| getLocalhostIP | | final public static byte[] getLocalhostIP()(Code) | | hopefully this will return the 'real' IP address even if the hosts file is configured
incorrectly (as I discovered on my test machine... JRB). However, If it really can't
figure out the address it will return the loopback address.

| sleep | | final public static void sleep(long time)(Code) | | |
