                                           Options.CreateOpts... opts)

Get an option of desired type

Parameters:

theClass - is the desired class of the opt

opts - - not null - at least one opt must be passed

Returns:

an opt from one of the opts of type theClass. returns null if there isn't any

setOpt

protected static <T extends Options.CreateOpts> Options.CreateOpts[] setOpt(T newValue,

set an option

Parameters:

newValue - the option to be set

opts - - the option is set into this array of opts

Returns:

updated CreateOpts[] == opts + newValue
