javax.annotation.processing
Interface Messager


public interface Messager

A Messager provides the way for an annotation processor to report error messages, warnings, and other notices. Elements, annotations, and annotation values can be passed to provide a location hint for the message. However, such location hints may be unavailable or only approximate.

Printing a message with an error kind will raise an error.

Note that the messages "printed" by methods in this interface may or may not appear as textual output to a location like System.out or System.err. Implementations may choose to present this information in a different fashion, such as messages in a window.
