operator == method

  1. @override
bool operator ==(
  1. covariant FileWrapper other
)
override

The equality operator.

The default behavior for all Objects is to return true if and only if this object and other are the same object.

Override this method to specify a different equality relation on a class. The overriding method must still be an equivalence relation. That is, it must be:

  • Total: It must return a boolean for all arguments. It should never throw.

  • Reflexive: For all objects o, o == o must be true.

  • Symmetric: For all objects o1 and o2, o1 == o2 and o2 == o1 must either both be true, or both be false.

  • Transitive: For all objects o1, o2, and o3, if o1 == o2 and o2 == o3 are true, then o1 == o3 must be true.

The method should also be consistent over time, so whether two objects are equal should only change if at least one of the objects was modified.

If a subclass overrides the equality operator, it should override the hashCode method as well to maintain consistency.

Implementation

@override
bool operator ==(covariant FileWrapper other) {
  // ignore: avoid_dynamic_calls
  if (other.content.runtimeType != content.runtimeType) return false;
  if (content is XFile && other.content is XFile) {
    final XFile f1 = content as XFile;
    final XFile f2 = other.content as XFile;
    return f1.name == f2.name || f1.path == f2.path;
  } else if (content is XUri && other.content is XUri) {
    final XUri u1 = content as XUri;
    final XUri u2 = other.content as XUri;
    return u1.uri == u2.uri;
  } else {
    return content == other.content;
  }
}
