equals()
or compareTo()
where an object is compared for equality
with itself.
According to the method contracts, these operations will always return
true
for equals()
or 0
for compareTo()
. The inspection also checks
the calls to Objects.equals()
, Objects.deepEquals()
,
Arrays.equals()
, Comparator.compare
, and the like.
Example:
class Foo {
boolean foo(Object o) {
return o.equals(o); // warning
}
boolean bar(String[] ss) {
return Arrays.equals(ss, ss); // warning
}
}
Use the option to report test assertions report only on non-extendable library classes (like String
) and primitive types.
This option could be useful, when tests check equals
methods.
