    • notifyObservers

      public void notifyObservers()
      If this object has changed, as indicated by the hasChanged method, then notify all of its observers and then call the clearChanged method to indicate that this object has no longer changed.

      Each observer has its update method called with two arguments: this observable object and null. In other words, this method is equivalent to:

      notifyObservers(null)
      See Also:

    • notifyObservers

      public void notifyObservers(Object arg)
      If this object has changed, as indicated by the hasChanged method, then notify all of its observers and then call the clearChanged method to indicate that this object has no longer changed.

      Each observer has its update method called with two arguments: this observable object and the arg argument.

      Parameters:
      arg - any object.
      See Also:

    • setChanged

      protected void setChanged()
      Marks this Observable object as having been changed; the hasChanged method will now return true.

    • clearChanged

      protected void clearChanged()
      Indicates that this object has no longer changed, or that it has already notified all of its observers of its most recent change, so that the hasChanged method will now return false. This method is called automatically by the notifyObservers methods.
      See Also:

    • hasChanged

      public boolean hasChanged()
      Tests if this object has changed.
      Returns:
      true if and only if the setChanged method has been called more recently than the clearChanged method on this object; false otherwise.

    • countObservers

      public int countObservers()
