Method Detail

handleTyping

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

Description copied from interface: AuthorSchemaAwareEditingHandler

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, AuthorSchemaAwareEditingHandler.handleTypingFallback(int, char, AuthorAccess) will get called.

Specified by:

handleTyping in interface AuthorSchemaAwareEditingHandler

Overrides:

handleTyping in class AuthorSchemaAwareEditingHandlerAdapter

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.

See Also:

AuthorSchemaAwareEditingHandlerAdapter.handleTyping(int, char, ro.sync.ecss.extensions.api.AuthorAccess)

handleTypingFallback

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

Description copied from interface: AuthorSchemaAwareEditingHandler

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

Specified by:

handleTypingFallback in interface AuthorSchemaAwareEditingHandler

Overrides:

handleTypingFallback in class AuthorSchemaAwareEditingHandlerAdapter

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.

AuthorSchemaAwareEditingHandlerAdapter.handleTypingFallback(int, char, ro.sync.ecss.extensions.api.AuthorAccess)

handlePasteFragment

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

Description copied from interface: AuthorSchemaAwareEditingHandler

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.

Specified by:

handlePasteFragment in interface AuthorSchemaAwareEditingHandler

Overrides:

handlePasteFragment in class AuthorSchemaAwareEditingHandlerAdapter

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.

See Also:

AuthorSchemaAwareEditingHandlerAdapter.handlePasteFragment(int, ro.sync.ecss.extensions.api.node.AuthorDocumentFragment[], int, ro.sync.ecss.extensions.api.AuthorAccess)

                                    java.lang.String elementLocalName)

Returns:

true if the given node is an element with the given local name and from the Docbook namespace.

changeElementsToMoveUpDown

public boolean changeElementsToMoveUpDown(java.util.List<AuthorNode> selectedElements)

Description copied from class: AuthorSchemaAwareEditingHandlerAdapter

Determine the elements that should be moved by the Move Up/Down operation. For example if the current selected element is a title then the element that should actually be moved is its parent (e.g. section for DocBook).

Overrides:

changeElementsToMoveUpDown in class AuthorSchemaAwareEditingHandlerAdapter

Parameters:

selectedElements - the selected elements in the author page. This list should be altered depending on the framework specific structure.
For example if the current selected element is a title then the element that should actually be present in this list is its parent (e.g. section for DocBook).

Returns:

true if the list of elements to be moved was altered by the framework specific handler.
