  - adjustPaymentDate
```
SwapPaymentEvent adjustPaymentDate(TemporalAdjuster adjuster)
```
    Adjusts the payment date using the rules of the specified adjuster.
    The adjuster is typically an instance of BusinessDayAdjustment. Implementations must return a new instance unless they are immutable and no change occurs.

    adjuster - the adjuster to apply to the payment date
    
    Returns:
    
    the adjusted payment event
  - isKnownAmountAt

    Parameters:
    
    date - the date to check whether payment amount is known or not
    
    Returns:
    
    true if payment is fixed at given date
