22 | * Service <code>tapestry.DeferredObjectTranslator</code>, which is used to encapsulate the |

23 | * ObjectTranslator and return {@link org.apache.tapestry.services.impl.DeferredObjectImpl}instances. |
|
24 | * These allow the translator to <em>not be executed until (and unless) |
|
25 | * the value is needed</em>, |
|
