Method Details

getDiscountCurveName

public String getDiscountCurveName()

Specified by:

getDiscountCurveName in interface ForwardCurve

Returns:

The name of the discount curve associated with this forward curve (e.g. OIS for collateralized forwards)

getPaymentOffset

public double getPaymentOffset(double fixingTime)

Description copied from interface: ForwardCurve

Returns the payment offset associated with this forward curve and a corresponding fixingTime.

Specified by:

getPaymentOffset in interface ForwardCurve
