Reclassifying gains/losses on cash flow hedge to P/L

Sir I find this easy to understand like if there is one off cash flow payment/receipt hedged, we will reclassify the gain/loss on the hedging instrument completely at the same time we recognise the cost/income from hedged item in P/L.

But in what way will we reclassify if the hedge is for something like a bond. Lets say a fixed interest rate swap for variable rate bond. We will be recognising interest income using the variable rate interest rate but by what amts. will we offset these changes in rates by reclassification.
Will it that we calculate the difference between the income that wud have been had the rate been fixed and the difference between the income already recognised and calculated using this will be charged or credited to P/L or something else?
