public class Document extends java.lang.Object implements DocListener
A generic Document class.All kinds of Text-elements can be added to a
HTMLDocument
. TheDocument
signals all the listeners when an element has been added.Remark:
- Once a document is created you can add some meta information.
- You can also set the headers/footers.
- You have to open the document before you can write content.
- You can only write content (no more meta-formation!) once a document is opened.
- When you change the header/footer on a certain page, this will be effective starting on the next page.
- Ater closing the document, every listener (as well as its
OutputStream
) is closed too.
