All Implemented Interfaces:

io.writeopia.sdk.backstack.BackstackHandler , io.writeopia.sdk.backstack.BackstackInform
```
public final class WriteopiaManager
 implements BackstackHandler, BackstackInform
                    
```
This is the entry class of the framework. It follows the Controller pattern, redirecting all the call to another class responsible for the part of the SDK requested.

```
  - saveOnStoryChanges
```
 final Unit saveOnStoryChanges(DocumentTracker documentTracker)
```
    Saves the document automatically as it is changed. It uses the DocumentTracker passed in the constructor of WriteopiaManager
  - isInitialized
```
 final Boolean isInitialized()
```
  - newStory
```
 final Unit newStory(String documentId, String title)
```
    Creates a new story. Use this when you wouldn't like to load a documented previously saved.
    
    Parameters:
    
    documentId - the id of the document that will be created
    
    title - the title of the document
  - initDocument
```
 final Unit initDocument(Document document)
```
    Initializes a document passed as a parameter. This method should be used when you would like to load a document from a database and start editing it, instead of creating something new.
    
    Parameters:
    
    document - Document
  - nextFocusOrCreate
```
 final Unit nextFocusOrCreate(Integer position)
```
    Moves the focus to the next available StoryStep if it can't find a step to focus, it creates a new StoryStep at the end of the document.
    
    Parameters:
    
    position - Int
  - mergeRequest
```
 final Unit mergeRequest(Action.Merge info)
```
    Merges two StoryStep into a group. This can be used to merge two images into a message group or any other kind of group.
    
    Parameters:
    
    info - Action.Merge
  - moveRequest
```
 final Unit moveRequest(Action.Move move)
```
    A request to move a content to a position.
    
    Parameters:
    
    move - Action.Move
  - changeStoryState
```
 final Unit changeStoryState(Action.StoryStateChange stateChange)
```
    At the moment it is only possible to check items not inside groups. Todo: Fix it!
    
    Parameters:
    
    stateChange - Action.StoryStateChange
  - changeStoryType
```
 final Unit changeStoryType(Integer position, StoryType storyType, CommandInfo commandInfo)
```
    Changes the story type. The type of a messages changes without changing the content of it. Commands normally change the type of a message. From a message to a unordered list item, for example.
    
    Parameters:
    
    position - Int
    
    storyType - StoryStep
    
    commandInfo - CommandInfo
  - onTextEdit
```
 final Unit onTextEdit(String text, Integer position)
```
    An text edition of a StoryStep
    
    Parameters:
    
    text - String
    
    position - Int
  - onTitleEdit
```
 final Unit onTitleEdit(String text, Integer position)
```
    An edition in title. Title edition also changes the meta data of a document.
    
    Parameters:
    
    text - String
    
    position - Int
  - onLineBreak
```
 final Unit onLineBreak(Action.LineBreak lineBreak)
```
    Creates a line break. When a line break happens, the line it divided into two StorySteps of the same, if possible, or the next line will be a Message.
    
    Parameters:
    
    lineBreak - Action.LineBreak
  - onSelected
```
 final Unit onSelected(Boolean isSelected, Integer position)
```
    Add a StoryStep of a position into the selection list. Selected content can be used to perform bulk actions, like bulk edition and bulk deletion.
  - clickAtTheEnd
```
 final Unit clickAtTheEnd()
```
    A click at the end of the document. The focus should be moved to the first StoryStep that can receive the focus, from last to first.
  - undo
```
 Unit undo()
```
    Undo the last action.
  - redo
```
 Unit redo()
```
    Redo the last undone action.
  - onDelete
```
 final Unit onDelete(Action.DeleteStory deleteStory)
```
    Deletes a StoryStep
    
    Parameters:
    
    deleteStory - Action.DeleteStory
  - deleteSelection
```
 final Unit deleteSelection()
```
    Deletes the whole selection. All StoryStep in the selection will be deleted.
  - onClear
