Names and values may be quoted or +// not. The quote '"' character must not be used within name or values, only for +// quoting whole tokens. You may use escape sequences wile parsing and add within a +// quoted token a \" to add quotes within your name or token. When using Escape +// Sequence the parser must now that by setting KeyValues::UsesEscapeSequences( true ), +// which it's off by default. Non-quoted tokens ends with a whitespace, '{', '}' and '"'. +// So you may use '{' and '}' within quoted tokens, but not for non-quoted tokens. +// An open bracket '{' after a key name indicates a list of subkeys which is finished +// with a closing bracket '}'. Subkeys use the same definitions recursively. +// Whitespaces are space, return, newline and tabulator. Allowed Escape sequences +// are \n, \t, \\, \n and \". The number character '#' is used for macro purposes +// (eg #include), don't use it as first character in key names. +//----------------------------------------------------------------------------- +class KeyValues +{ +private: + KeyValues(); // for internal use only + +public: + // Constructors/destructors + KeyValues(const char* pszSetName); + KeyValues(const char* pszSetName, const char* pszFirstKey, const char* pszFirstValue); + KeyValues(const char* pszSetName, const char* pszFirstKey, const wchar_t* pwszFirstValue); + KeyValues(const char* pszSetName, const char* pszFirstKey, int iFirstValue); + KeyValues( + const char* pszSetName, const char* pszFirstKey, const char* pszFirstValue, const char* pszSecondKey, const char* pszSecondValue); + KeyValues(const char* pszSetName, const char* pszFirstKey, int iFirstValue, const char* pszSecondKey, int iSecondValue); + ~KeyValues(void); + + void Init(void); + void Clear(void); + void DeleteThis(void); + void RemoveEverything(); + + KeyValues* FindKey(const char* pKeyName, bool bCreate = false); + KeyValues* FindLastSubKey(void) const; + + void AddSubKey(KeyValues* pSubkey); + void RemoveSubKey(KeyValues* pSubKey); + void InsertSubKey(int nIndex, KeyValues* pSubKey); + bool ContainsSubKey(KeyValues* pSubKey); + void SwapSubKey(KeyValues* pExistingSubkey, KeyValues* pNewSubKey); + void ElideSubKey(KeyValues* pSubKey); + + // Data access + bool IsEmpty(const char* pszKeyName); + KeyValues* GetFirstTrueSubKey(void) const; + KeyValues* GetNextTrueSubKey(void) const; + KeyValues* GetFirstValue(void) const; + KeyValues* GetNextValue(void) const; + KeyValues* GetFirstSubKey() const; + KeyValues* GetNextKey() const; + const char* GetName(void) const; + int GetInt(const char* pszKeyName, int iDefaultValue); + uint64_t GetUint64(const char* pszKeyName, uint64_t nDefaultValue); + void* GetPtr(const char* pszKeyName, void* pDefaultValue); + float GetFloat(const char* pszKeyName, float flDefaultValue); + const char* GetString(const char* pszKeyName = nullptr, const char* pszDefaultValue = ""); + const wchar_t* GetWString(const char* pszKeyName = nullptr, const wchar_t* pwszDefaultValue = L""); + Color GetColor(const char* pszKeyName, const Color& defaultColor); + KeyValuesTypes_t GetDataType(const char* pszKeyName); + KeyValuesTypes_t GetDataType(void) const; + + // Key writing + void SetInt(const char* pszKeyName, int iValue); + void SetUint64(const char* pszKeyName, uint64_t nValue); + void SetPtr(const char* pszKeyName, void* pValue); + void SetNextKey(KeyValues* pDat); + void SetName(const char* pszName); + void SetString(const char* pszKeyName, const char* pszValue); + void SetWString(const char* pszKeyName, const wchar_t* pwszValue); + void SetStringValue(char const* pszValue); + void SetColor(const char* pszKeyName, Color color); + void SetFloat(const char* pszKeyName, float flValue); + + void RecursiveCopyKeyValues(KeyValues& src); + void CopySubkeys(KeyValues* pParent) const; + KeyValues* MakeCopy(void) const; + +public: + uint32_t m_iKeyName : 24; // 0x0000 + uint32_t m_iKeyNameCaseSensitive1 : 8; // 0x0003 + char* m_sValue; // 0x0008 + wchar_t* m_wsValue; // 0x0010 + union // 0x0018 + { + int m_iValue; + float m_flValue; + void* m_pValue; + unsigned char m_Color[4]; + }; + char m_szShortName[8]; // 0x0020 + char m_iDataType; // 0x0028 + char m_bHasEscapeSequences; // 0x0029 + uint16_t m_iKeyNameCaseSensitive2; // 0x002A + KeyValues* m_pPeer; // 0x0030 + KeyValues* m_pSub; // 0x0038 + KeyValues* m_pChain; // 0x0040 +}; -- cgit v1.2.3
