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.

Since:
1.6

Method Summary
 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
