Member Function Documentation

◆ compounding()

Compounding compounding ( ) const

Definition at line 66 of file flatforward.hpp.

◆ compoundingFrequency()

Frequency compoundingFrequency ( ) const

Definition at line 67 of file flatforward.hpp.

◆ maxDate()

Date maxDate ( ) const
overridevirtual

the latest date for which the curve can return values

Implements TermStructure.

Definition at line 71 of file flatforward.hpp.

+ Here is the call graph for this function:

◆ update()

void update ( )
overridevirtual

This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes.

Reimplemented from LazyObject.

Definition at line 97 of file flatforward.hpp.

+ Here is the call graph for this function:

◆ performCalculations()

void performCalculations ( ) const
overrideprivatevirtual

This method must implement any calculations which must be (re)done in order to calculate the desired results.

Implements LazyObject.

Definition at line 107 of file flatforward.hpp.

+ Here is the call graph for this function:

◆ discountImpl()

DiscountFactor discountImpl ( Time  ) const
overrideprivatevirtual

discount factor calculation

Implements YieldTermStructure.
