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).

A PDF object can be a simple type, like a Boolean, a Number, a String, or the Null value. It can also be a NAME, which looks like a string, but is a special type in PDF files, like "/Name".
A PDF object can also be complex types, including Array; Dictionary; Stream, which is a Dictionary plus an array of bytes; or Indirect, which is a reference to some other PDF object. Indirect references will always be dereferenced by the time any data is returned from one of the methods in this class. @author Mike Wessler
