  The default accessor for writing a value and listening to changes that is used by a <a href='Control-class.html'><code>Control</code></a> directive.
  
  This is the default strategy that Angular uses when no other accessor is applied.
  
   # Example
   ```
   <input type="text" [control]="loginControl">
   ```

  h2 Members
  .l-sub-section

    pre.prettyprint
      code.
        constructor()
