    • convert

      public final Object convert(DataTypeDefinition propertyType, Object value)
      General conversion method to Object types (note it cannot support conversion to primary types due the restrictions of reflection. Use the static conversion methods to primitive types)

      propertyType - - the target property type
      value - - the value to be converted
      Returns:
      - the converted value as the correct type

    • convert

      public final <T> T convert(Class<T> c, Object value)
      General conversion method to Object types (note it cannot support conversion to primary types due the restrictions of reflection. Use the static conversion methods to primitive types)
      Type Parameters:
      T - The target type for the result of the conversion
      Parameters:
