SuppressWarnings
implements
Annotation
| java.lang.SuppressWarnings
|
Indicates that the named compiler warnings should be suppressed in the
annotated element (and in all program elements contained in the annotated
element). Note that the set of warnings suppressed in a given element is
a superset of the warnings suppressed in all containing elements. For
example, if you annotate a class to suppress one warning and annotate a
method to suppress another, both warnings will be suppressed in the method.
As a matter of style, programmers should always use this annotation
on the most deeply nested element where it is effective. If you want to
suppress a warning in a particular method, you should annotate that
method rather than its class.

The set of warnings that are to be suppressed by the compiler in the

value
public String[] value ()
The set of warnings that are to be suppressed by the compiler in the
annotated element. Duplicate names are permitted. The second and
successive occurrences of a name are ignored. The presence of
unrecognized warning names is not an error: Compilers must
ignore any warning names they do not recognize. They are, however,
free to emit a warning if an annotation contains an unrecognized
warning name.
The string "unchecked" is used to suppress
unchecked warnings. Compiler vendors should document the
additional warning names they support in conjunction with this
annotation type. They are encouraged to cooperate to ensure
that the same names work across multiple compilers.
