  • Method Details

    • decorate

      void decorate(B builder, T optionValue)
      Provides the ability to decorate option as it is being set on the target builder. This method is invoked from within the setter of the value before the value is set on the builder (i.e. the builder still contains previous value). Do not call the same setter again from within this method, as it would end in a stack overflow.
      Parameters:
      builder - the target builder being decorated
      optionValue - option value set by the caller of the setter method

    • decorateSetList

      default void decorateSetList(B builder, List<T> optionValues)

      Parameters:
      builder - the target builder being decorated
      optionValues - option values set by the caller of the setter method

    • decorateAddList

      default void decorateAddList(B builder, List<T> optionValues)

      Parameters:
      builder - the target builder being decorated

    • decorateSetSet

      default void decorateSetSet(B builder, Set<T> optionValues)
