I used the following code to copy data in the object “item” to “pkt” $cast(pkt,item); Then I have performed an operation on “pkt” object. But I observed that same changes are appearing on “item” also when I printed the content. But this is not happening when I used copy() method that is available…

In reply to bachan21 : $cast(pkt,item) is copying the handle, not the object. After executing this statement, put and item are two class variables containing the same class handle. See A Short Class on SystemVerilog Classes - Verification Horizons
