Understanding Anonymous Methods in Delphi

By March 20, 2012

Follow me on:

in Delphi Language :: In short, an anonymous method is a procedure or function that does not have a name associated with it. Anonymous methods extend existing procedural types and by allowing you use the actual code of a method as a parameter to some other method. In addition, an anonymous method can refer to variables and bind values to the variables in the context in which the method is defined.

I would NOT recommend the use of anonymous method(s), first because the code is less readable and second I can see a lot of problems while debugging code with anonymous method(s).
In short if you DO use them, try to keep them as short as possible ~ 5-10 lines max…

I do think that anonymous methods are useful; but as everything in life, you have to know when to apply them. Here’s another article about anonymous methods in Delphi.

Pascal has had procedural types for a long time. A type is defined as a procedure or function. A variable is defined as this type before assigning a procedure (or function) to this variable. From the examples I only see a syntactic difference between this older strategy and the newer “anonymous methods”. Maybe the examples I looked at are too simple. Is there an advantage using anonymous methods over procedural types?
