ajax.h

词法分析的程序。核心函数是一个状态切换的函数 CAjaxParserDlg::Route。状态切换函数解根据一个 DFA 来对输入的文本进行分析。也就是说

// ajax
#include <afxtempl.h>

struct CHAR_RANGE{
	BYTE byStart;
	BYTE byEnd;
};

#define STATE_START		1
#define STATE_END		2

struct DFA_STATE{
	DWORD	nFlag;
};

typedef CArray<DFA_STATE, DFA_STATE&> StateArray;

#define ROUTE_BUF_LEN		4
class CStateChangeRule
{
public:
	void Clear();
	CStateChangeRule();
	~CStateChangeRule();

	int	nCurState;
	int nNextState;
	CHAR_RANGE route[ROUTE_BUF_LEN];
};

typedef CArray <CStateChangeRule, CStateChangeRule&> StateChangeRuleArray;
