There is no getOption, but rather getInstrument, where Instrument is the
base class (or interface). Position contains an Instrument, of which there
are subclasses like EquityInstrument, CashInstrument, OptionInstrument,
FixedIncomeInstrument, etc. As you suspected, there are not many subtypes
(say 20).
