RoundEnvironment (Java Platform SE 8 )

```
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

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and 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.
`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 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.
    
    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
  - 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 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.
    
    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
