By definition, primitive types are not Objects and so they can't be null
. Adding @CheckForNull
or @Nullable
on primitive types adds confusion and is useless.
This rule raises an issue when @CheckForNull
or @Nullable
is set on a method returning a primitive type: byte, short,
int, long, float, double, boolean, char.
@CheckForNull boolean isFoo() { ... }
boolean isFoo() { ... }
