Interface DeterministContract

All Superinterfaces:

FixedExchangeMarkovContract, FixedExchangeMomentsContract, GeneralContract, RegularPayoffContract, Serializable

All Known Implementing Classes:

CouponBond, DeterministContractCommon, ZeroCouponBond

public interface DeterministContract

extends RegularPayoffContract

This interface defines a contract of a fixed-income security. A contract on a fixed-income security is one where we know in advance the exact dates and amounts of the cash flows resulting from holding the contract.

You should never implement this interface directly. If you wish to define a contract on a fixed-interest security (i.e. a FixedExchangeMomentsContract) then you should extend the abstract class FixedExchangeMomentsContractCommon.

Advantages of using this interface

Contracts which implement this interface have an enormous advantage when considerning pricing algorithm efficiency. Unfortunately only few contracts have the required properties to be implemented as DeterministicContract instances. If the contract is not a fixed income security you need to look for more general abstract classes to extend. These are, ordered from the least general to most generally applicable: FixedExchangewMarkovContracCommon, FixedExchangeMomentsContractCommon, GeneralContractCommon

Method Summary

double

getPayoff(int moment) Returns the value of the cash exchange (payoff) occcuring at the moment indentified by its index in the vector of payoff moments (the vector returned by the method getMoments()).
