From SmartMessageConverter

fromMessage Object fromMessage(MessageBase message, TypeInfo targetClass, TypeInfo conversionHint): A variant of {@link #fromMessage(Message, Class)} which takes an extra conversion context as an argument, allowing to take e.g. annotations on a payload parameter into account. @param message the input message @param targetClass the target class for the conversion @param conversionHint an extra object passed to the {@link MessageConverter}, e.g. the associated {@code MethodParameter} (may be {@code null}} @return the result of the conversion, or {@code null} if the converter cannot perform the conversion @see #fromMessage(Message, Class)
fromMessage alias fromMessage = MessageConverter.fromMessage: Undocumented in source.
toMessage MessageBase toMessage(Object payload, MessageHeaders headers, TypeInfo conversionHint): A variant of {@link #toMessage(Object, MessageHeaders)} which takes an extra conversion context as an argument, allowing to take e.g. annotations on a return type into account. @param payload the Object to convert @param headers optional headers for the message (may be {@code null}) @param conversionHint an extra object passed to the {@link MessageConverter}, e.g. the associated {@code MethodParameter} (may be {@code null}} @return the new message, or {@code null} if the converter does not support the Object type or the target media type @see #toMessage(Object, MessageHeaders)
toMessage alias toMessage = MessageConverter.toMessage: Undocumented in source.
