| Interface | Description | 
|---|---|
| Completion | A suggested completion for an
 annotation. | 
| Filer | This interface supports the creation of new files by an annotation
 processor. | 
| Messager | A  Messagerprovides the way for an annotation processor to
 report error messages, warnings, and other notices. | 
| ProcessingEnvironment | An annotation processing tool framework will provide an annotation processor with an object
 implementing this interface so the processor can use facilities
 provided by the framework to write new files, report error
 messages, and find other utilities. | 
| Processor | The interface for an annotation processor. | 
| 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. | 
| Class | Description | 
|---|---|
| AbstractProcessor | An abstract annotation processor designed to be a convenient
 superclass for most concrete annotation processors. | 
| Completions | Utility class for assembling  Completionobjects. | 
| Exception | Description | 
|---|---|
| FilerException | Indicates a  Filerdetected an attempt to open a file that
 would violate the guarantees provided by theFiler. | 
| Annotation Type | Description | 
|---|---|
| SupportedAnnotationTypes | An annotation used to indicate what annotation types an annotation
 processor supports. | 
| SupportedOptions | An annotation used to indicate what options an annotation processor
 supports. | 
| SupportedSourceVersion | An annotation used to indicate the latest source version an
 annotation processor supports. | 
Unless otherwise specified in a particular implementation, the collections returned by methods in this package should be expected to be unmodifiable by the caller and unsafe for concurrent access.
