performance issue with parameter passing by value/reference

Hi.. Is there any performance issue while passing the parameter by value/reference in methods? How efficient is both the method (passing by value/reference)? Thanks!

     Hi MVSI,

     

    This depends on the situation, but in generalt any method that works with "big" parameters (think class objects/structs/units/lists/arrays) will benefit from passing by reference. Just make the tradeoff in evaluating both the method call and method execution: Does it matter whether the 'object' (in any sense) is "close by" on the stack, or there's only a pointer to the object "far away" in memory? In general people choose for pointers/references when dealing with anything "big".

     

    Good luck and I hope this helps a bit,

    Hilmar
