de.julielab.concepts.db.application.OptionalStringArrayOptionHandler

public class OptionalStringArrayOptionHandler
extends org.kohsuke.args4j.spi.OptionHandler<String>

Works just like StringArrayOptionHandler with the exception that the original handler returns a null value if no arguments are given to the parameter. It is this not determinable if the parameter was given but without arguments or not given at all. This handler will add the empty string in case that no arguments are given but the parameter is still present. IMPORTANT: This means that you will have to check for empty argument values when using this handler.
