isA<T extends JObject?> method

bool isA<T extends JObject?>(JObjType<T> type)

Whether this object is of the given type ignoring the type parameters.

Warning

Because of Java generic type erasure, this method cannot distinguish between two classes Foo<A> and Foo<B> as they are both of type Foo. Therefore, object.isA(Foo.type(A.type)) will return a false-positive true for objects of type Foo<B> as well.

For example:

if (object.isA(JLong.type)) {
  final i = object.as(JLong.type).longValue;
  ...
}

Implementation

bool isA<T extends JObject?>(JObjType<T> type) {
  final targetJClass = type.jClass;
  final canBeCasted = isInstanceOf(targetJClass);
  targetJClass.release();
  return canBeCasted;
}
