Structured Stream Class!*//***	(c) COPYRIGHT MIT 1995.**	Please first read the full copyright statement in the file COPYRIGH.*//*The Structured stream class defines objects which accepts a structuredsequence of characters for eaxmple a SGML document. I'll rephrase that. Astructured object is am ordered tree-structured arrangement of data whichis representable as text. An example is the SGML parserwhich outputs to a Structured Object. A Structured object can output itscontents to another Structured Object. It's a kind of typedstream. The architecure is largely Dan Conolly's. Elements and entities arepassed to the sob by number, implying a knowledge of the DTD.The Structured Stream is a subclass of aGeneric Stream Object. As always, we don't haveclasses in basic C so we have to do this by hand!This module is a part of the W3C Sample Code Library.*/#ifndef HTSTRUCT_H#define HTSTRUCT_H#include "HTStream.h"#include "HTList.h"/**/typedef struct _HTStructured HTStructured;typedef struct _HTStructuredClass {    char * name;    int (*flush)	(HTStructured * me);    int (*_free)	(HTStructured *	me);    int (*abort)	(HTStructured *	me, HTList * errorlist);    int (*put_character)(HTStructured *	me, char ch);    int (*put_string)	(HTStructured *	me, const char * str);    int (*put_block)	(HTStructured * me, const char * str, int len);/*See the Generic Stream Definition for an explanationof these methods.
