      public org.springframework.binding.convert.ConversionService getConversionService()
      Description copied from interface: FlowBuilderContext
      Returns a generic type conversion service for converting between types, typically from string to a rich value object.
      Specified by:
      getConversionService in interface FlowBuilderContext
      Returns:
      the generic conversion service

    • getViewFactoryCreator

    • createConversionService

      protected org.springframework.binding.convert.ConversionService createConversionService()
      Factory method that creates the conversion service the flow builder will use. Subclasses may override. The default implementation registers Web Flow-specific converters thought to be useful for most builder implementations, setting the externally-provided builder services conversion service as its parent.
      Returns:
      the flow builder conversion service
