= Analysis =

== Overview ==
 * After the task the saving and loading books feature should be fixed.

== Task requirements ==

After this task the following results will be visible:

 * Saving and loading books will be available.
 * Backward compatibility with the older books (books using the old text model) will be available.
 * Copy/Paste of (styled) text will  be available.
 * Drag/Drop of (styled) text will be available
 * Rtf/Html import/export will be available.
 * The server collaboration will be available with the text resources.
This features will work not worse than the existing ones in the trunk.

== Task result ==

The result will be code.

== Implementation idea ==
 * Create persisters for the new classes and fix the old ones.

== Related ==
^(Add links to related tasks that could be useful or helpful.)^

== How to demo ==
 * Create a new book in sophie. Save the book. Close the book. Load the book again.
 * Create a new book in sophie. Create text frame, type text. Copy the text, paste the text.
 * Create a new book in sophie. Create a text resource. Drag and drop the resource in sophie.
 * Create a new book in sophie. Import html or rtf document.

//--------BASE_PERSISTER_PART--------------------

In order to achieve this functionallity the following changes have been made: 
 * In TextRun class add new function : public HotStyleDef getRunStyles() - retrieves the
 styles that the run contains and returns the styles of the TextRun. This is needed in the persister class
 of the TextRun (TextRunPersister).
 * In HotStyleDef class add new function : public ImmMap<HotAttr<?>, Object> getValues() -
 getter for all attributes that the current HotStyleDef consists of, returns the current HotStyleDef
 values for the contained attributes. This is needed while persisting the HotStyleDef objects(in 
 HotStyleDefPersister class).
 * In ImmMap interface add new function: Map<K, V> toMap() - gets the Map for the current ImmMap 
 and returns a Map view of the ImmMap. This is needed because HotStyleDef#derive
(Map<HotAttr<?>, Object> styleValues) takes Map and while persisting the HotStyleDef
 we have only ImmMap available.
 * Implement the toMap() function in ImmTreeMap class.
 * In org.sophie2.base.model.text.persistence add new classes: 
   * public class HotStyleDefPersister extends RefToStoragePersister<HotStyleDef> - persister for
 HotStyleDef class. It persists the Map  of the HotAttr<?> -> Object of the HotStyleDef objects.
  * public class TextRunPersister extends RefToStoragePersister<TextRun> - persister for TextRun class.
  It persists the text of the TextRun as string and it's HotStyleDef.
  * public class ImmHotTextPersister extends RefToStoragePersister<ImmHotText> - persister for ImmHotText class.
  It persists the ImmHotText as follows: gets the TextRun-s of the text and persists them.
 * Rename the HotTextIntervalPersister to ImmTextIntervalPersister.
