Configuring an Extensions Bundle

public String getDocumentTypeID() {
    return "Simple.Document.Framework.document.type";
}

public String getDescription() {
    return "A custom extensions bundle used for the Simple Document" + 
           "Framework document type";
}

public AuthorExtensionStateListener createAuthorExtensionStateListener() {
    return new SDFAuthorExtensionStateListener();
}

The AuthorExtensionStateListener is instantiated and notified about the activation of the framework when the rules of the Document Type Association match a document opened in the Author editing mode. The listener is notified about the deactivation when another framework is activated for the same document, the user switches to another mode or the editor is closed. A complete description and implementation of ro.sync.ecss.extensions.api.AuthorExtensionStateListener can be found in Implementing an Author Extension State Listener.

If Schema-Aware mode is active in Oxygen XML Author, all actions that can generate invalid content will be redirected toward the ro.sync.ecss.extensions.api.AuthorSchemaAwareEditingHandler. The handler can resolve a specific case, let the default implementation take place, or reject the edit entirely by throwing ro.sync.ecss.extensions.api.InvalidEditException. The actions that are forwarded to this handler include typing, delete, or paste.

For more details about this handler, see Handling Schema-Aware Editing Events.

public SchemaManagerFilter createSchemaManagerFilter() {
    return new SDFSchemaManagerFilter();
}

A detailed presentation of the schema manager filter can be found in the Configuring a Content Completion Handler section.

public ElementLocatorProvider createElementLocatorProvider() {
    return new DefaultElementLocatorProvider();
}

For more information on how to implement an element locator provider, see the Configuring a Link Target Element Finder section.

public AuthorDnDListener createAuthorAWTDndListener() {
    return new SDFAuthorDndListener();
}

For more details about the Author mode drag and drop listeners, see the Configuring a custom Drag and Drop Listener section.

public AuthorReferenceResolver createAuthorReferenceResolver() {
    return new ReferencesResolver();
}

A more detailed description of the references resolver can be found in the Configuring a References Resolver section.

public StylesFilter createAuthorStylesFilter() {
    return new SDFStylesFilter();
}

See the Configuring CSS Styles Filter section for more details about the styles filter extension.

public AuthorTableCellSpanProvider createAuthorTableCellSpanProvider() {
    return new TableCellSpanProvider();
}

public AuthorTableColumnWidthProvider 
    createAuthorTableColumnWidthProvider() {
    return new TableColumnWidthProvider();
}

The two table information providers are not reused for different tables. The methods are called for each table in the document so new instances should be provided every time. Read more about the cell span and column width information providers in Configuring a Table Cell Span Provider and Configuring a Table Column Width Provider sections.

If the functionality related to one of the previous extension points does not need to be modified, then the developed ro.sync.ecss.extensions.api.ExtensionsBundle should not override the corresponding method and leave the default base implementation to return null.

public LinkTextResolver createLinkTextResolver() {
  return new DitaLinkTextResolver();
}

Oxygen XML Author offers built-in implementations for DITA and DocBook: ro.sync.ecss.extensions.dita.link.DitaLinkTextResolver and ro.sync.ecss.extensions.docbook.link.DocbookLinkTextResolver respectively.
