Method Detail

getPayLegPricer
```
protected DiscountingSwapLegPricer getPayLegPricer()
```
Gets the pay leg pricer.

Returns:

the pay leg pricer

```
Calculates the present value of the Ibor cap/floor product.
The present value of the product is the value on the valuation date.
The cap/floor leg and pay leg are typically in the same currency, thus the present value gamma is expressed as a single currency amount in most cases.

Parameters:

capFloor - the Ibor cap/floor product

ratesProvider - the rates provider

volatilities - the volatilities

Returns:

the present value

Calculates the present value for each caplet/floorlet of the Ibor cap/floor product.

The present value of each caplet/floorlet is the value on the valuation date. The result is returned using the payment currency of the leg.

The present value will not be calculated for the pay leg if the product has one.
