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>, | |
26 | * with the added expense that you have to de-referrence the | |
27 | * {@link org.apache.tapestry.services.impl.DeferredObjectImpl}. | |
