public interface ProcessingEnvironment
Third parties may wish to provide value-add wrappers around the
facility objects from this interface, for example a
extension that allows multiple processors to coordinate writing out
a single source file. To enable this, for processors running in a
context where their side effects via the API could be visible to
each other, the tool infrastructure must provide corresponding
facility objects that are
Filers that are
.equals, and so on. In addition, the tool invocation must
be able to be configured such that from the perspective of the
running annotation processors, at least the chosen subset of helper
classes are viewed as being loaded by the same class loader.
(Since the facility objects manage shared state, the implementation
of a wrapper class must know whether or not the same base facility
object has been wrapped before.)
|Modifier and Type||Method and Description|
Returns an implementation of some utility methods for operating on elements
Returns the filer used to create new source, class, or auxiliary files.
Returns the current locale or
Returns the messager used to report errors, warnings, and other notices.
Returns the processor-specific options passed to the annotation processing tool.
Returns an implementation of some utility methods for operating on types.
See documentation of the particular tool infrastructure
being used for details on how to pass in processor-specific
options. For example, a command-line implementation may
distinguish processor-specific options by prefixing them with a
known string like
"-A"; other tool implementations may
follow different conventions or provide alternative mechanisms.
A given implementation may also provide implementation-specific
ways of finding options passed to the tool in addition to the
