Sample code

Suppose you have the following class definition.

1:

class handleA

2:

open method void THandler(dictionary dic)

3:

... // event handler code.

4:

endmethod

5:

endclass

6:

class handleB

7:

open method void THandler(dictionary dic)

8:

... // event handler code.

9:

endmethod

10:

endclass

Usage of the Handler setter is as follows.

1:

handleA ha = new handleA();

2:

handleB hb = new handleB();

3:

timer tim = new timer(ha, "THandler(dictionary)", 1000); // It sets the instance of the handleA class.

4:

tim.Handler = hb; // It changes the instance to the handleB class.

In the above code, Handler instances are different class, but these have the method with same signature, so it works fine.
