The DataDirector
interface includes the following methods for which all presentation beans require an implementation:
addDataDirectorListener
removeDataDirectorListener
The following table lists methods that you can implement in the DataDirector
interface in order to provide specific data manipulation capabilities. The table indicates the presentation beans to which each method applies.

Not all data sources support all types of data manipulation. For example, the BI Beans data source does not support the reorder
or setOutline
methods. You decide which data manipulation methods you will implement in the DataDirector
interface by considering the functionality that your application requires.
