Here are some examples:. It basically invokes that function for each value in the list and returns another list containing the results of the function invocations. That is, the lambda expression can coerce to any interface or abstract class which has declared only one abstract method. Sometimes this is not what you want. Consequently, you can use if expressions deeply nested within expressions:.

Xtend is a statically typed programming language sitting on top of Java. To do so use the new project wizard and in the category Xtend Examples choose the active annotation example.
Xtend Hello World
. Have a look at the Java doc for more details. Depending on which Java language version is chosen, Xtend might generate different but equivalent code. For example, lambda expressions are translated to.
Annotations are available on classes, fields, methods and parameters.
Xtend Java Interoperability
An annotation Lazy which turns fields into lazily initialized properties, may be used like this:. Although this code is execute during transform, the actual concatenation only happens during code generation.
Null-Safe Feature Calls Checking for null references can make code very unreadable. The Data annotation will turn the class into an immutable value class, that is it will get.
Xtend Active Annotations
There are no octal numbers. This is the main problem with model transformations.

There are many nice examples and.
In Java you often see code like this:. A validation for that case would be sensible, too. On the result of the split operation, the method iterator is invoked. Annotation processors that implement TransformationParticipant participate in this compile step. The hello world example is translated to the following Java code:.
