Document (iText-4.2.1 4.2.1 API)

java.lang.Object
- com.lowagie.text.Document

All Implemented Interfaces:: DocListener, ElementListener, EventListener

Direct Known Subclasses:: PdfDocument

public class Document
extends Object
implements DocListener

A generic Document class.

All kinds of Text-elements can be added to a HTMLDocument. The Document 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.
After closing the document, every listener (as well as its OutputStream) is closed too.

Example:

// creation of the document with a certain size and certain margins
 Document document = new Document(PageSize.A4, 50, 50, 50, 50);
  try { 
   // creation of the different writers 
   HtmlWriter.getInstance(document , System.out);
   PdfWriter.getInstance(document , new FileOutputStream("text.pdf"));
   // we add some meta information to the document
   document.addAuthor("Bruno Lowagie"); 
   document.addSubject("This is the result of a Test."); 
   // we open the document for writing
   document.open(); 
   document.add(new Paragraph("Hello world"));
  } catch(DocumentException de) {
   System.err.println(de.getMessage());
  }
  document.close();
