CompileStatic (Groovy 5.0.0)

Package: groovy.transform

## [Java] Annotation Type CompileStatic

- groovy.transform.CompileStatic

-     @Retention(RetentionPolicy.SOURCE)
      @Target({ElementType.TYPE,ElementType.METHOD,ElementType.CONSTRUCTOR})
      @GroovyASTTransformationClass("org.codehaus.groovy.transform.sc.StaticCompileTransformation")
      public @interface CompileStatic

  This will let the Groovy compiler use compile time checks in the style of Java then perform static compilation, thus bypassing the Groovy meta object protocol.

  When a class is annotated, all methods, properties, files, inner classes, etc. of the annotated class will be type checked. When a method is annotated, static compilation applies only to items (closures and anonymous inner classes) within the method.

  By using TypeCheckingMode.SKIP, static compilation can be skipped on an element within a class or method otherwise marked with CompileStatic. For example a class can be annotated with CompileStatic, and a method within can be marked to skip static checking to use dynamic language features.
