Class MultipageModel

java.lang.Object

diva.gui.MultipageModel

public class MultipageModel
extends Object

A document that contains a linear sequence of Pages. This class is useful for documents which their data into logical pages. Generally this class is most useful for partitioned documents where all the partitions are stored together. For partitions that are stored separately, it is probably easiest to just use separate documents. Note that a page can contain any kind of data, and the interpretation and graphical representation of a list of page is up to the concrete document class and the corresponding application. Other than containing a sequence of pages, this class is used the same as AbstractDocument and provides the same abstract methods.
