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).

the 'size' of the object. The definition of 'size' depends on the object type. In particular: For a dictionary or a stream object, the method will return the number of key/value pairs in the dictionary. For an array object the method will return the number of Obj enties in the array. For a string object the method will return the number of bytes in the string buffer. For any other object the method will always return 1.
