I am writing an article on metaprogramming and have several questions on
Groovy. I would thank any help with them.
1. Is there any example in which @GroovyASTTransformationClass takes an
array with more
than one element? Something like this:
@Retention(RetentionPolicy.SOURCE)
@Target([ElementType.TYPE])
@GroovyASTTransformationClass( [FirstTransformation,
SecondTransformation] )
@interface MyAnnot { }
I could not find one. If this is possible, I suppose that a single annotation
can apply transformations in several compiler phases.
2. Suppose I want to use the annotation WithLogging of
http://groovy-lang.org/metaprogramming.html#developing-ast-xforms
All I have is the Groovy compiler, a .exe file. What do I do? The general
question is: how the Groovy compiler finds a **local** AST transformation
class? For global transformation the page above says
Compiled classes that implement global transformations are in a JAR added to
the classpath of the compiler and contain service locator file META-INF...
But for local transformations, there is no such observation.
