Public Methods

Method	Description
IsIntType ( CseObject data ) : bool	Determines if value passed in is an integral-type
NarrowIntType ( CseObject xdata ) : CseObject	Changes the given integral-type object to the smallest integral data type that can contain its value. If xdata has a CompileTimeType that is unsigned, then the smallest unsigned integral type is used. Otherwise the smallest signed type is used. The only current exception to this is byte vs. sbyte as they are considered special cases and therefore, regardless if the original type is unsigned or not, byte is always attempted in place of sbyte.
ParseEscSeqs ( string &data, bool isVerbatim ) : void	Parses escape sequences found in char or string literals

Private Methods

Method	Description
IsUnsignedType ( CseObject xdata ) : bool	Determines whether the xdata's CompileTimeType is an unsigned integral type or not
ParseBool ( string data ) : CseObject	Parses bool literals
ParseChar ( string data ) : CseObject	Parses char literals
ParseEType ( string data ) : CseObject	Parses literals that contain the exponential 'e' character
ParseFloatType ( string data, bool hasSuffix ) : CseObject	Parses float-type literals
ParseFloatType ( string data, string suffix ) : CseObject	Parses float-type literals
ParseIntType ( string data, bool hasSuffix ) : CseObject	Parses integral-type literals
ParseIntType ( string data, string suffix ) : CseObject	Parses integral-type literals
ParseStr ( string data ) : CseObject	Parses string literals

Method Details

IsIntType() public static method

Determines if value passed in is an integral-type

public static IsIntType ( CseObject data ) : bool
data	CseObject	Value to examine
return	bool

NarrowIntType() public static method

Changes the given integral-type object to the smallest integral data type that can contain its value. If xdata has a CompileTimeType that is unsigned, then the smallest unsigned integral type is used. Otherwise the smallest signed type is used. The only current exception to this is byte vs. sbyte as they are considered special cases and therefore, regardless if the original type is unsigned or not, byte is always attempted in place of sbyte.

public static NarrowIntType ( CseObject xdata ) : CseObject
xdata	CseObject	Integral-type value to narrow
return	CseObject

ParseEscSeqs() public static method

Parses escape sequences found in char or string literals

public static ParseEscSeqs ( string &data, bool isVerbatim ) : void
data	string	String containing the literal that may have escape sequences
isVerbatim	bool	/// Used to tell if the literal passed is a verbatim string. /// True if data represents verbatim string, false otherwise ///
return	void
