## Interface ComponentAction<T>

- All Superinterfaces:
    `Serializable`
  All Known Implementing Classes:
    `BeanEditor.Prepare`

      public interface ComponentAction<T>
      extends Serializable

  An action that is associated with a component. This is used in several areas of Tapestry and is primarily an attempt to externalize state for a component so that it can be recorded outside the object. ComponentActions should be immutable. They are often created during one request and associated with a particular component instance. They are then used in a later request (with an equivalent component instance). ComponentActions are serializable (they are often serialized into Base64 strings for storage on the client).
