31 * A programmer assertion that the body of the annotated method or
32 * constructor does not perform potentially unsafe operations on its
33 * varargs parameter. Applying this annotation to a method or
34 * constructor suppresses unchecked warnings about a
35 * <i>non-reifiable</i> variable arity (vararg) type and suppresses
36 * unchecked warnings about parameterized array creation at call
39 * <p> In addition to the usage restrictions imposed by its {@link
40 * Target @Target} meta-annotation, compilers are required to implement
41 * additional usage restrictions on this annotation type; it is a
42 * compile-time error if a method or constructor declaration is
43 * annotated with a {@code @SafeVarargs} annotation, and either:
45 * <li> the declaration is a fixed arity method or constructor
47 * <li> the declaration is a variable arity method that is neither
48 * {@code static} nor {@code final}.
52 * <p> Compilers are encouraged to issue warnings when this annotation
53 * type is applied to a method or constructor declaration where:
57 * <li> The variable arity parameter has a reifiable element type,
58 * which includes primitive types, {@code Object}, and {@code String}.
59 * (The unchecked warnings this annotation type suppresses already do
60 * not occur for a reifiable element type.)
62 * <li> The body of the method or constructor declaration performs
63 * potentially unsafe operations, such as an assignment to an element
64 * of the variable arity parameter's array that generates an unchecked
65 * warning. Some unsafe operations do not trigger an unchecked
66 * warning. For example, the aliasing in
69 * @SafeVarargs // Not actually safe!
70 * static void m(List<String>... stringLists) {
71 * Object[] array = stringLists;
72 * List<Integer> tmpList = Arrays.asList(42);
73 * array[0] = tmpList; // Semantically invalid, but compiles without warnings
74 * String s = stringLists[0].get(0); // Oh no, ClassCastException at runtime!
78 * leads to a {@code ClassCastException} at runtime.
80 * <p>Future versions of the platform may mandate compiler errors for
81 * such unsafe operations.
