Method Detail

printProgressBar

public static void printProgressBar(int stat)

Prints outa progress bar on stdout. To use it properly you should create a new thread which contains the code whom status you want to display. Then you can print out the status by calling this method in a loop.

Parameters:

stat - the status (percent completed)

mergeArrays

public static java.lang.String[] mergeArrays(java.lang.String[] a,
                                             java.lang.String[] b)

Merges two String arrays, sorts them and removes double Strings.

Parameters:

a - the first array

b - the second array

Returns:

the new array

getNumberOfLines

public static int getNumberOfLines(java.lang.String s)

Returns the number of lines contained in a string.

Parameters:

s - the string

Returns:

the number of lines

parseCMDLine

public static java.lang.String[] parseCMDLine(java.lang.String[] a,
                                              java.util.Properties p)

Parses cmdline options. The cmdline options should start with `-'. You must provide this method a properties object where the default values should be stored. It must also contain all possible options. You can use switches like `-m', the properties value should then be "true"/"false". Normal cmdline options can have an argument (in the properties should then be any other value than "true"/"false"). The String-array that is returned contains "-false-" if there was a parse error. If not, it contains additional arguments that don't belong to options (like filenames) at the end of the cmdline. Note that a typical key/value pair in the properties object could look like that: "-o","foofile" or "-z","true".

Parameters:

a - the args[] array from the main method

p - the properties containing the defaults

Returns:

an array with additional arguments (null if there are none)
