  • Method Details

    • useRecycled

      public Object useRecycled()
      The most recently recycled value. It can be used exactly once.

    • recycle

      public void recycle(Object value)

    • setCurrentRoot

      public void setCurrentRoot(Key<?> rootEntity)
      Sets the current root entity

    • done

      public void done()
      Call this when a load process completes. Executes anything in the batch and then executes any delayed operations.

    • loadRef

      public <T> Ref<T> loadRef(Key<T> key, LoadConditions loadConditions)
      Create a Ref for the key, and maybe start a load operation depending on current load groups.

    • defer

      public void defer(Runnable runnable)
      Delays an operation until the context is done(). Typically this is for lifecycle methods.

    • getContainer

      public Object getContainer(Type containerType, Path path)
      Get the container object which is appropriate for the specified property. Go up the chain looking for a compatible type; the first one found is the container. If nothing found, throw an exception.

    • enterContainerContext

      public void enterContainerContext(Object container)
      Enter a container context; this is the context of the object that we are processing right now.

    • exitContainerContext

      public void exitContainerContext(Object expectedContainer)
      Exit a container context. The parameter is just a sanity check to make sure that the value popped off is the same as the value we expect.
