    • removeObject

      public void removeObject(NSObject obj)
      Removes an object from the set.
      Parameters:
      obj - The object to remove.

    • allObjects

      public NSObject[] allObjects()
      Returns all objects contained in the set.
      Returns:
      An array of all objects in the set.

    • anyObject

      public NSObject anyObject()
      Returns one of the objects in the set, or null if the set contains no objects.
      Returns:
      The first object in the set, or null if the set is empty.

    • containsObject

      public boolean containsObject(NSObject obj)
      Finds out whether the given object is contained in the set.
      Parameters:
      obj - The object to look for.
      Returns:
      true, when the object was found, false otherwise.

    • member

      public NSObject member(NSObject obj)
      Determines whether the set contains an object equal to the given object and returns that object if it is present.
      Parameters:
      obj - The object to look for.
      Returns:
      The object if it is present, null otherwise.

    • intersectsSet

      public boolean intersectsSet(NSSet otherSet)
      Finds out whether at least one object is present in both sets.
      Parameters:
      otherSet - The other set.
      Returns:
      false if the intersection of both sets is empty, true otherwise.

    • isSubsetOfSet

      public boolean isSubsetOfSet(NSSet otherSet)
      Finds out if this set is a subset of the given set.
      Parameters:
      otherSet - The other set.
      Returns:
      true if all elements in this set are also present in the other set, false otherwise.

    • objectIterator

      public Iterator<NSObject> objectIterator()
      Returns an iterator object that lets you iterate over all elements of the set. This is the equivalent to objectEnumerator in the Cocoa implementation of NSSet.
      Returns:
