## Interface ThunkCreator

- All Known Implementing Classes:
    ThunkCreatorImpl

      public interface ThunkCreator

  A thunk is a delayed calculation. In Java and Tapestry terms, a Thunk is a proxy object of a particular interface that delegates all methods to an object of the same type obtained from an `ObjectProvider`. This is used by `LazyAdvisor` to build lazy thunk proxies.
  Since:
    5.1.0.1
