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.

Since:

1.6

Method Summary

Modifier and Type	Method	Description
`boolean`	`errorRaised()`	Returns `true` if an error was raised in the prior round of processing; returns `false` otherwise.
`Set<? extends Element>`	`getElementsAnnotatedWith(Class<? extends Annotation> a)`	Returns the elements annotated with the given annotation type.
`Set<? extends Element>`	`getElementsAnnotatedWith(TypeElement a)`	Returns the elements annotated with the given annotation type.
`default Set<? extends Element>`	`getElementsAnnotatedWithAny(Set<Class<? extends Annotation>> annotations)`	Returns the elements annotated with one or more of the given annotation types.
`default Set<? extends Element>`	`getElementsAnnotatedWithAny(TypeElement... annotations)`	Returns the elements annotated with one or more of the given annotation types.
`Set<? extends Element>`	`getRootElements()`	Returns the root elements for annotation processing generated by the prior round.
`boolean`	`processingOver()`	Returns `true` if types generated by this round will not be subject to a subsequent round of annotation processing; returns `false` otherwise.

- Method Detail
  - 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 type. 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, or type parameters 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 type being requested
    
    Returns:
    
    the elements annotated with the given annotation type, or an empty set if there are none
    
    Throws:
    
    IllegalArgumentException - if the argument does not represent an annotation type
  - getElementsAnnotatedWithAny
```
default Set<? extends Element> getElementsAnnotatedWithAny(TypeElement... annotations)
```
    Returns the elements annotated with one or more of the given annotation types.
    
    API Note:
    
    This method may be useful when processing repeating annotations by looking for an annotation type and its containing annotation type at the same time.
    
    Implementation Requirements:
    
    The default implementation of this method creates an empty result set, iterates over the annotations in the argument array calling getElementsAnnotatedWith(TypeElement) on each annotation and adding those results to the result set. Finally, the contents of the result set are returned as an unmodifiable set.
    
    Parameters:
    
    annotations - annotation types being requested
    
    Returns:
    
    the elements annotated with one or more of the given annotation types, or an empty set if there are none
    
    Throws:
    
    IllegalArgumentException - if the any elements of the argument set do not represent an annotation type

  - getElementsAnnotatedWith
```
Set<? extends Element> getElementsAnnotatedWith(Class<? extends Annotation> a)
```
    Returns the elements annotated with the given annotation type. 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, or type parameters 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 type as a Class object to a different representation used for annotation processing. The set of annotation types present in the runtime context may differ from the set of annotation types present in the context of annotation processing in a particular environmental configuration. If an runtime annotation type is not present in the annotation processing context, the situation is not treated as an error and no elements are found for that annotation type.
    
    Parameters:
    
    a - annotation type being requested
    
    Returns:
    
    the elements annotated with the given annotation type, or an empty set if there are none
    
    Throws:
    
    IllegalArgumentException - if the argument does not represent an annotation type

default Set<? extends Element> getElementsAnnotatedWithAny(Set<Class<? extends Annotation>> annotations)

    Returns the elements annotated with one or more of the given annotation types.
