    • getPrinter

      Printer<?> getPrinter(A annotation, Class<?> fieldType)
      Get the Printer to print the value of a field of fieldType annotated with annotation.

      If the type T the printer accepts is not assignable to fieldType, a coercion from fieldType to T will be attempted before the Printer is invoked.

      Parameters:
      annotation - the annotation instance
      fieldType - the type of field that was annotated
      Returns:
      the printer

    • getParser

      Parser<?> getParser(A annotation, Class<?> fieldType)
      Get the Parser to parse a submitted value for a field of fieldType annotated with annotation.

      If the object the parser returns is not assignable to fieldType, a coercion to fieldType will be attempted before the field is set.

      Parameters:
      annotation - the annotation instance
      fieldType - the type of field that was annotated
      Returns:
      the parser
