Gets a command to update a table of contents.
readonly updateTableOfContents: UpdateTableOfContentsCommand
A UpdateTableOfContentsCommand object that provides methods for executing the command and checking its state.
You can invoke this command by calling the execute method.
The execute method checks the command state (obtained using the getState method) before executing, and decides whether the action can be performed. The execute and getState methods are members of the UpdateTableOfContentsCommand class.
Use the updateTableOfContents command to update the table of contents after its entries have been changed. If the current selection includes several tables of contents, the method updates the first one.
