All Implemented Interfaces:

Serializable

public class RaccoonTransformer
extends ViewTransformer

This implementation utilizes Raccoon server for formatting view. Raccoon server must be correctly configurated and provide access both via. Internet interface and local directory. Whole process of transforming is realized by transform() method in the following manner:

1. Received DataModel object is written in the directory Raccoon server provides for storing temporary models.
2. Raccoon server is called via URL address to transform file with model according to the action name (suggested by ModelConstructor or PersonalModelConstructor) and type of media, users have to access the system.
3. Eventually temporary file with model is removed and response returned from Raccoon server is put into DataView object and returned.
