public static boolean allParametersWereUsed()

processCommandLineArguments

public static void processCommandLineArguments(java.lang.String[] argv)

Parse a String[] of command-line arguments. The syntax of an argument is -name=value. The value assigned to a name can the be obtained as a String by calling getParameter("name"). Other get-methods can return values of other types.

If no value is given, the value is the empty string "". For getBoolean(name), this is equivalent to "true".

The syntax -not name, or -no name, is equivalent to -name=false.

The syntax -load filename can be used to read parameter values from a file. The file should contain lines in name=value syntax.

loadParameters

public static void loadParameters(java.lang.String filename)
