virtual ~Object ()
 The destructor is defined as virtual (but not abstract), so that destruction of Object's works properly.
 
virtual bool equals (Object *other)
 Returns, whether two objects are equal.
 
virtual int hashValue ()
 Return a hash value for the object.
 
virtual Objectclone ()
 Return an exact copy of the object.
 
virtual void intoStringBuffer (misc::StringBuffer *sb)
 Store a textual representation of the object in a misc::StringBuffer.
 
const char * toString ()
 Use object::Object::intoStringBuffer to return a textual representation of the object.
 
virtual size_t sizeOf ()
 Return the number of bytes, this object totally uses.
