Page

Direct Known Subclasses:

AbstractHTMLPage
```
public abstract class AbstractPage
extends Object
implements Page
```
Abstract implementation of Page .
Contains base methods for storing and accessing page properties. Also stores pageData as byte[] and implements write???() methods.

Concrete implementations need only set the pageData and call addProperty(java.lang.String,java.lang.String) to add all the required information.
