title: What is the name of this pattern or technique?
body: <p>There are objects which need two other objects as parameters. This parameter objects may change during runtime. </p>
  
  <p>I use another object which holds the references to the parameter objects. These references are always up to date. </p>
  
  <p>All the other objects ask this objects for the current parameters. They don't have to be updated anymore. Only this "reference helper" will be updated. </p>
  
  <p>What is the name of this pattern or technique, or the name of the "reference helper"? </p>
  
  <p>Edit: Here is a Java example:</p>
  
  <pre><code>class ReferenceHelper {
  
      private Parameter parameter;
  
      public ReferenceHelper(Parameter parameter){setParameter(parameter);}
  
      public Parameter getParameter(){return parameter;}
      public void setParameter(Paramater parameter){ this.parameter = parameter;}
  
  }
  </code></pre>
  
  <p>P.S. I know its almost a bean, but thats not the point, because it has a special purpose.</p>
