Annotation Type PlatformLog

@Documented
@Retention(SOURCE)
@Target(TYPE)
public @interface PlatformLog

This local transform adds a logging ability to your program using java.logging. Every method call on a unbound variable named log will be mapped to a call to the logger. For this a log field will be inserted in the class. If the field already exists the usage of this transform will cause a compilation error. The method name will be used to determine what to call on the logger.

 @PlatformLog
 class Foo {
     def method() {
         log.log INFO, 'Foobar'
     }
 }

 new Foo().method()
