## Class RetainWorker

- java.lang.Object
- - org.apache.tapestry5.internal.transform.RetainWorker

- All Implemented Interfaces:
    `ComponentClassTransformWorker2`

      public final class RetainWorker
      extends java.lang.Object
      implements ComponentClassTransformWorker2

  Identifies fields with the `Retain` annotation, and "claims" them so that no special work will occur on them. Retain has been deprecated in Tapestry 5.2 and will likely be removed in the future.
