Possible heap pollution from parameterized vararg type
Warning
New
Last modified: 03 December 2024 Reports methods with variable arity, which can be annotated as @SafeVarargs
. The @SafeVarargs
annotation suppresses unchecked warnings about parameterized array creation at call sites.
Example:
public class Foo<T> {
private List<T> list = new ArrayList<>();
public final void safeVarargs(T... elements) {
Collections.addAll(list, elements);
}
}
After the quick-fix is applied:
public class Foo<T> {
private List<T> list = new ArrayList<>();
@SafeVarargs
public final void safeVarargs(T... elements) {
Collections.addAll(list, elements);
}
}
This annotation is not supported under Java 1.6 or earlier JVMs.
