@surial
lifting
■ Roel Spilker
@rspilker ■ Developers just have to

7. GROOVY AST TRANSFORMATIONS
Where, Who, How Why?
■ https:// ■ Groovy plays nicely with
groovy.codehaus.org Java
■ The Groovy Team ■ Compile time
metaprogramming
executes faster than
■ Compile time runtime
metaprogramming ■ Changes visible to other
■ Changes registered in the JVM languages
bytecode

8. HOW DOES IT LOOK?
The @Immutable AST transformation makes writing
immutable classes trivial

■ @Bindable / @Vetoable ■ @Delegate
■ @Grab ■ @Log
■ @Immutable ■ @Synchronized
■ @AutoClone
■ @Singleton
■ @AutoExternalize
■ @ToString
■ @EqualsAndHashCode ■ @TypeChecked
