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:

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

handleTyping

 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

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.

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

getLastResult

@Deprecated
public SchemaAwareHandlerResult getLastResult()

Deprecated.

Will be removed in a future version

Returns:

The result generated by the last handler method invoked before this call. Is null if event was not handled.

 int endOffset,
 int creationPurposeID,
 AuthorAccess authorAccess)
                                                    throws BadLocationException

Description copied from interface: AuthorSchemaAwareEditingHandler

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

Specified by:

handleDeleteNodes in interface AuthorSchemaAwareEditingHandler

Parameters:

nodes - The nodes to delete.

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.

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

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.

See Also:

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

changeElementsToMoveUpDown

public boolean changeElementsToMoveUpDown(List<AuthorNode> selectedElements)

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).

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.

Since:

15.2

getAncestorDetectionOptions

public AuthorSchemaAwareEditingHandlerAdapter.WrapInAncestorsOptions getAncestorDetectionOptions()

One of the default smart paste strategies involves detecting an path o ancestors from the context element to the inserted one. These are the preferences that control how these ancestors are chosen.

Returns:

Preferences for choosing the best possible ancestors while building a path.

Since:

18

canBeReplaced

public boolean canBeReplaced(AuthorNode nodeToReplace)

When pasting an element inside an empty element with the same name, a possible solution is to replace the empty node with the new one. This callback has a chance of rejecting this behavior when, for example, the node to replace has important attributes set on it.

Parameters:

nodeToReplace - The node to replace.

Returns:

true if this node can be replaced by the strategy with a similar one. false if this node is important and must be kept in the document.

Since:

18

getPreferredElement

public QName getPreferredElement(AuthorDocumentController ctrl,
 int offset)

Get the qualified name of the best element to be inserted at the caret position as a wrapper for the content that is being typed or pasted.

Parameters:

ctrl - Provides methods for modifying the Author document.

offset - The caret offset where the insertion is performed.

Returns:

the qualified name of the preferred element or null.
