as<T extends JObject> method

T as<T extends JObject>(JType<T> type, { bool releaseOriginal = false, })

Casts this object to another type.

If releaseOriginal is true, the casted object will be released.

Throws CastError if this object is not an instance of type.

Implementation

T as<T extends JObject>(
  JType<T> type, {
  bool releaseOriginal = false,
}) {
  if (!isA(type)) {
    throw CastError('not a subtype of "${type.signature}"');
  }

  if (releaseOriginal) {
    final ret =
        JObject.fromReference(JGlobalReference(reference.pointer)) as T;
    reference.setAsReleased();
    return ret;
  }
  final newRef = JGlobalReference(Jni.env.NewGlobalRef(reference.pointer));
  return JObject.fromReference(newRef) as T;
}
