Lambdas in Salesforce Apex

Question

Does Apex support the concept of lambdas?

Ultimately, I am trying to DRY up some really repetitive code in my tests, so I'd love to be able to pass functions around, something like this (C#-esq)

public static TestMethod void some_test_method(){
  Arrange( ()=>
    // some setup stuff
  );
  Act( ()=>
    // test action
  );
  System.assertEquals(...);
}

Answer 1

Apex doesn't have lambdas. In fact, it doesn't even have anonymous classes. (That would have been your next question.) You're going to have to stick with declared classes. Apex does support Java-ish interfaces and abstract classes.

You can try R.apex(https://github.com/Click-to-Cloud/R.apex) for a functional stylish programming, although you still have to use declared classes.
