TODO STUDVA recoment

Is a View, is a true compound editor, composites of IEditors.

This class houses instances of IEditors: chooses from available, creates and/or destroys instances of IEditors when required and creates and positions Composites for them.

Is is also ISelectionProvider and owns XMLSelection. Other IXMLSelectionProviders refernces this XMLSelection, modifies it and send changes back to EditorSite through methods setSelection(...) or selectionChanged(...)

Is also responsible for loading, transforming, saving. Main functionality is driven by GENE.

Acts as view in MultiViewXMLEditor.

                 throws EditorException

Description copied from interface: IEditorDataReceiver

Editor site instance receives data change events using this method.

Parameters must NOT be changed. For more info on the parameters see GeneDataProvider class.

Specified by:

dataChanged in interface IEditorDataReceiver

Parameters:

rendererKeys - Maps input pipe ID to a renderer instance. Shows current state - keys recently deleted (keys present in the deletedKeys set) are not present.

rootKey - The root key of the hierarchy. It is not expected to be changed between dataChanged calls, only in extreme situation when whole document is scraped and recreated.

nametreeHierarchy - The nametree (key) hierarchy. Maps key to a set of its children. If key is missing from the map, maps to null value or an empty set then the nametree does not have any children. Shows current state - keys recently deleted (keys present in the deletedKeys set) are not present.

geneIdMapping - Maps GENE-generated ids to the coordinator input key instance. Used by renderer context to map from GENE id (provided to the renderer) to child renderer instance. Shows current state - keys recently deleted (keys present in the deletedKeys set) are not present.

newKeys - Contains set of new keys (keys that were not introduced in previous GENE output processing).

deletedKeys - Contains set of keys that were introduced in previous GENE output processing but they are missing in current data.

Throws:

EditorException - if fatal exception occurs. Editor errors should be handled by the receiver properly (for example by replacing the editor canvas with an Error banner).
