From AS3 to C#, Part 17: Conditionals, Exceptions, and Iterators

Tags: , , , , , , , , , , ,

Continuing the series on C# syntax, today we’ll look at the differences an AS3 programmer can expect to encounter when using conditionals (if/else, switch/case/break/goto) and exceptions (try/catch/finally/throw). We’ll also look at iterators, an all-new category for AS3 programmers that empowers us to both iterate however we want and to write coroutines, a kind of lightweight pseudo-thread.

If-Else Trees vs. Array and Vector

Tags: , , , , , ,

We’ve seen that if-else trees are way faster than Object, Dictionary, and even switch at key-value mapping, but how do they stack up against Array and Vector? Today’s article puts them to the test and uncovers some unexpected results.

ASC 2.0 Conditionals Performance

Tags: , , , , , , , ,

Surprisingly, some interesting things have been happening with conditionals like if-else in AS3. First, a brand new AS3 compiler—ASC 2.0—has been released with the promise that it’ll generate more efficient bytecode. Second, some readers have pointed out the existence of a new (to me) technique: the “if-else tree”. Today’s article takes a look at just what that is and tests it against the classic options: if-else, the ternary (? :) operator, and the switch statement. Which will be fastest?

Conditionals Performance Revisited

Tags: , , , , , ,

Today I’m revisiting an article I wrote last August about conditionals: if-else chains, ternary (? :) operators, and switch statements. In that article I showed that if-else chains are about as fast as ternary operators and that both of them are 10-15% faster than switch statements. Today we’ll take a look at how those conditionals scale beyond just the few cases in the last article.

Conditionals Performance

Tags: , , , , , ,

Now that the Flash Player 10.1 testing is through I can return to a comment asking about the performance difference between if-else chains and the ternary (? :) operator. Further, I’ll discuss switch statements to see if there is any difference in performance for these commonly-used methods of flow control.

Case Statements

Tags: , , ,

The lowly switch statement and its attendant case statements is a basic element of most C-style languages. Still, I was surprised by it recently when it seemingly ate one of my functions. Read on to see how.
