public abstract class PdfObject
extends Object
```
PdfObject is the abstract superclass of all PDF objects.
PDF supports seven basic types of objects: Booleans, numbers, strings, names, arrays, dictionaries and streams. In addition, PDF provides a null object. Objects may be labeled so that they can be referred to by other objects.
All these basic PDF objects are described in the 'Portable Document Format Reference Manual version 1.3' Chapter 4 (pages 37-54).
