21. Delegati in dogodki

22. Delegati Delegates are reference types which allow indirect calls to methods. A delegate instance holds references to some number of methods, and by invoking the delegate one causes all of these methods to be called. The usefulness of delegates lies in the fact that the functions which invoke them are blind to the underlying methods they thereby cause to run (see, for instance, the discussion of events, below).

23. Delegati From this brief description, it can be seen that delegates are functionally rather similar to C++'s 'function pointers'. However, it is important to bear in mind two main differences. Firstly, delegates are reference types rather than value types. Secondly, some single delegates can reference multiple methods

24. Delegate Declaration and Instantiation Each delegate is limited to referencing methods of a particular kind only. The type is indicated by the delegate declaration - the input parameters and return type given in the delegate declaration must be shared by the methods its delegate instances reference. To illustrate this: a delegate specified as below can be used to refer only to methods which have a single String input and no return value: public delegate void Print (String s);

25. Suppose, for instance, that a class contains the following method: public void realMethod (String myString){    // method code } Another method in this class could then instantiate the 'Print' delegate in the following way, so that it holds a reference to 'realMethod': Print delegateVariable = new Print(realMethod);

26. Jezikovna podpora dogodkom Ključna beseda event nam omogoča določiti delegata, ki bo ustrezal poklicanim metodam ob nastopu nekega dogodka.public event AlarmEventHandler Alarm; Dogodek sprožimo s klicem dogodkaAlarm(); Odjemalci se prijavijo na dogodek z operatorjem += eventSource.Alarm += new AlarmEventHandler(eventListener.AlarmRang); Razredi - dogodki

47. Atributi

48. Atributi so deklarativni elementi jezika pridevniki so na primer tudi deklarativni elementi omogočajo dekoracijo elementov kode z dodatno informacijo assembly, modul, tip, član tipa, return value, parameter Atributi posplošujejo koncept deklarativnega elementa atributi niso omejeni na vnaprej določeno množico lahko se zmišljujemo svoje nove atribute atributi in njihove vrednosti so dosegljivi v času prevajanja in v času izvajanja Atributi [Obsolete("This class is obsolete")] class A { public void F() {} }
