readArg

protected void readArg(String arg)

Description copied from class: OptionsList.Option

Converts an argument to the correct value type, and acts on the value.

What action is taken depends upon whether the value is valid for this argument type, and whether there is a handler. If there is a handler, this method calls either OptionsList.OptionHandler.set(org.eigenbase.util.OptionsList.Option, java.lang.Object, boolean) or OptionsList.OptionHandler.invalidValue(org.eigenbase.util.OptionsList.Option, java.lang.String). If there is no handler, the method should execute a reasonable default action like assigning to a field via reflection.
