Class Obj

Obj is a concrete class for all SDF/Cos objects. Obj hierarchy implements the composite design pattern. As a result, you can invoke a member function of any 'derived' object through Obj interface. If the member function is not supported (e.g. if you invoke Obj::GetNumber() on a boolean object) an Exception will be thrown.

You can use GetType() or obl.Is???() member functions to find out type-information at run time, however most of the time the type can be inferred from the PDF specification. Therefore when you call Doc::GetTrailer() you can assume that returned object is a dictionary. If there is any ambiguity use Is???() methods.

Objects can't be shared across documents, however you can use Doc::ImportObj() to copy objects from one document to another.

Objects can be shared within a document provided that they are created as indirect. Indirect objects are the ones that are referenced in cross-reference table. To create an object as indirect use Doc::CreateIndirect???() (where ? is the Object type).
