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.
