/**
* Resolved FX (European) single barrier option.
* <p>
* An FX option is a financial instrument that provides an option to exchange two currencies at a specified future time
* only when barrier event occurs (knock-in option) or does not occur (knock-out option).
* <p>
* Depending on the barrier defined in {@link Barrier}, the options are classified into four types: up-and-in,
* down-and-in, up-and-out and down-and-out.
* <p>
* For example, an up-and-out call on a 'EUR 1.00 / USD -1.41' exchange with barrier of 1.5 is the option to
* perform a foreign exchange on the expiry date, where USD 1.41 is paid to receive EUR 1.00, only when EUR/USD rate does
* not exceed 1.5 during the barrier event observation period.
* <p>
* In case of the occurrence (non-occurrence for knock-in options) of the barrier event, the option becomes worthless,
* or alternatively, a rebate is made.
