Interface RoundEnvironment


public interface RoundEnvironment
An annotation processing tool framework will provide an annotation processor with an object implementing this interface so that the processor can query for information about a round of annotation processing.

  • Method Details

    • processingOver

      boolean processingOver()
      Returns true if types generated by this round will not be subject to a subsequent round of annotation processing; returns false otherwise.
      Returns:
      true if types generated by this round will not be subject to a subsequent round of annotation processing; returns false otherwise
    • errorRaised

      boolean errorRaised()
      Returns true if an error was raised in the prior round of processing; returns false otherwise.
      Returns:
      true if an error was raised in the prior round of processing; returns false otherwise
    • getRootElements

      Set<? extends Element> getRootElements()
      Returns the root elements for annotation processing generated by the prior round.
      Returns:
      the root elements for annotation processing generated by the prior round, or an empty set if there were none
    • getElementsAnnotatedWith

      Set<? extends Element> getElementsAnnotatedWith(TypeElement a)
      Returns the elements annotated with the given annotation interface. The annotation may appear directly or be inherited. Only package elements, module elements, and type elements included in this round of annotation processing, or declarations of members, constructors, parameters, type parameters, or record components declared within those, are returned. Included type elements are root types and any member types nested within them. Elements of a package are not considered included simply because a package-info file for that package was created. Likewise, elements of a module are not considered included simply because a module-info file for that module was created.
      Parameters:
      a - annotation interface being requested
      Returns:
      the elements annotated with the given annotation interface, or an empty set if there are none
      Throws:
      IllegalArgumentException - if the argument does not represent an annotation interface
    • getElementsAnnotatedWithAny

      default Set<? extends Element> getElementsAnnotatedWithAny(TypeElement... annotations)
      Returns the elements annotated with one or more of the given annotation interfaces.
      Parameters:
      annotations - annotation interfaces being requested
      Returns:
      the elements annotated with one or more of the given annotation interfaces, or an empty set if there are none
      Throws:
      IllegalArgumentException - if the any elements of the argument set do not represent an annotation interface

    • getElementsAnnotatedWith

      Set<? extends Element> getElementsAnnotatedWith(Class<? extends Annotation> a)
      Returns the elements annotated with the given annotation interface. The annotation may appear directly or be inherited. Only package elements, module elements, and type elements included in this round of annotation processing, or declarations of members, constructors, parameters, type parameters, or record components declared within those, are returned. Included type elements are root types and any member types nested within them. Elements in a package are not considered included simply because a package-info file for that package was created. Likewise, elements of a module are not considered included simply because a module-info file for that module was created.

      Note: An implementation of this method typically performs an internal conversion from the runtime reflective representation of an annotation interface as a Class object to a different representation used for annotation processing. The set of annotation interfaces present in the runtime context may differ from the set of annotation interfaces present in the context of annotation processing in a particular environmental configuration. If an runtime annotation interface is not present in the annotation processing context, the situation is not treated as an error and no elements are found for that annotation interface.

      Parameters:
      a - annotation interface being requested
      Returns:
      the elements annotated with the given annotation interface, or an empty set if there are none
      Throws:
      IllegalArgumentException - if the argument does not represent an annotation interface

      default Set<? extends Element> getElementsAnnotatedWithAny(Set<Class<? extends Annotation>> annotations)
      Returns the elements annotated with one or more of the given annotation interfaces.

      Throws:
