Interface AuthorSchemaAwareEditingHandler

All Known Implementing Classes:

AuthorSchemaAwareEditingHandlerAdapter, DITASchemaAwareEditingHandler, Docbook5SchemaAwareEditingHandler, DocbookSchemaAwareEditingHandler, TEISchemaAwareEditingHandler

@API(type=EXTENDABLE,
     src=PUBLIC)
public interface AuthorSchemaAwareEditingHandler

If Schema Aware mode is active in Oxygen, all actions that can generate invalid content will be redirected toward this handler. The handler can either resolve a specific case, let the default implementation take place or reject the edit entirely by throwing an InvalidEditException.

It is recommended to extend class AuthorSchemaAwareEditingHandlerAdapter in order to be protected from any API additions that may occur in interface AuthorSchemaAwareEditingHandler.

Handle a keyboard delete event at the given offset (using Delete or Backspace keys) in the Author edit area.

Parameters:

                          throws InvalidEditException

Handle a delete nodes event coming from the Outline or Bread crumb.

Parameters:

deleteType - ACTION_ID_DELETE if the nodes were deleted directly by the user or ACTION_ID_DND if the nodes were deleted as a result of a drag and drop move operation in the Outline.

authorAccess - Access class to the author functions.

Returns:

true if the event was handled.

Throws:

InvalidEditException - This is an invalid edit and must be rejected.

handleDeleteSelection

boolean handleDeleteSelection(int selectionStart,
                              int selectionEnd,
                              int generatedByActionId,
                              AuthorAccess authorAccess)
                              throws InvalidEditException

Handle a delete selection event in the Author edit area. The event is generated when a selection exists inside the document and one of following actions takes place:

• typing (insert a new character in document by typing);
• cut;
• DND move;
• delete or backspace.

Parameters:

selectionStart - Selection start offset.

selectionEnd - Selection end offset.

generatedByActionId - An id identifying the action that generated this event. One of the following constants are possible: ACTION_ID_TYPING, ACTION_ID_DELETE, ACTION_ID_PASTE, ACTION_ID_CUT, ACTION_ID_DND, ACTION_ID_INSERT_FRAGMENT.

authorAccess - Access class to the author functions.

Returns:

true if the event was handled.

Throws:

InvalidEditException - This is an invalid edit and must be rejected.

handlePasteFragment

boolean handlePasteFragment(int offset,
                            AuthorDocumentFragment[] fragmentsToInsert,
                            int actionId,
                            AuthorAccess authorAccess)
                            throws InvalidEditException

Handle an insert fragment event generated by:

• a Paste action. In this case, selection removal is handled before calling this method.
• a DND action. In this case source removal is handled after calling this method (unless an exception was thrown).
• an insert fragment event occurred as a result of an schema aware insert event, like AuthorDocumentController.insertXMLFragmentSchemaAware(String, int). Selection removal is handled before calling this method.

Parameters:

offset - Offset where the event occurred.

fragmentsToInsert - Fragments to be inserted.

actionId - ACTION_ID_PASTE if event was generated by paste action, ACTION_ID_DND if it was generated by a DND event or ACTION_ID_INSERT_FRAGMENT if the event was generated by an AuthorDocumentController schema aware insert method.

authorAccess - Access class to the author functions.

Returns:

true if the insertion was handled.

Throws:

InvalidEditException - This is an invalid edit and must be rejected.

handleTyping

boolean handleTyping(int offset,
                     char ch,
                     AuthorAccess authorAccess)
                     throws InvalidEditException

Handle a typing event. If the event is not handled, the default implementation of a handler will be given a chance to handle the event. If that fails to provide a solution, handleTypingFallback(int, char, AuthorAccess) will get called.

Parameters:

offset - Offset where the typing occurred.

ch - The typed character.

authorAccess - Access class to the author functions.

Returns:

code>true if the typing was handled.

Throws:

InvalidEditException - This is an invalid edit and must be rejected.

handleTypingFallback

boolean handleTypingFallback(int offset,
                             char ch,
                             AuthorAccess authorAccess)
                             throws InvalidEditException

Give a fallback solution for a typing event. This call comes when this object's handleTyping(int, char, AuthorAccess) method did not handle the typing event and neither did the handleTyping(int, char, AuthorAccess) from the default implementation.

As a fallback solution, a paragraph can be inserted at the given offset (if allowed) and then the typed character can be inserted inside it.

Parameters:

offset - Offset where the typing occurred.

ch - The typed character.

authorAccess - Access class to the author functions.

Returns:

true if the typing was handled.

Throws:

InvalidEditException - This is an invalid edit and must be rejected.

Since:

13.2

boolean handleDeleteElementTags(AuthorNode nodeToUnwrap,
                                AuthorAccess authorAccess)
                                throws InvalidEditException

Handle delete element tags event. (Unwrapping)

Parameters:

nodeToUnwrap - The node to delete element tags.

authorAccess - Access class to the author functions.

Returns:

code>true if the event was handled.

Throws:

InvalidEditException - This is an invalid edit and must be rejected.

handleJoinElements

boolean handleJoinElements(AuthorNode targetNode,
                           java.util.List<AuthorNode> nodesToJoin,
                           AuthorAccess authorAccess)
                           throws InvalidEditException

Handle a join event between the given nodes.

Parameters:

targetNode - The node where the content of the other nodes must migrate.

nodesToJoin - The nodes that must be joined in the target node.

authorAccess - Access class to the author functions.

Returns:

true if the event was handled.

handleCreateDocumentFragment

AuthorDocumentFragment handleCreateDocumentFragment(int startOffset,
                                                    int endOffset,
                                                    int creationPurposeID,
