Public Methods

Method	Description
Canonicalize ( string source, int startIndex ) : string	Take a possibly escaped character literal and convert it to a canonical form. Thus @"'\377'", @"'\xff'" and @"'\u00FF'" all return @"'\xFF'". Throws a StringInterpretException if character ordinal exceeds "symLimit".
InterpretCharacterEscapes ( string source ) : string	This static method expands characters in a literal string, returning a modified string with character escapes replaced by the character which they denote. This includes characters outside the BMP which return a pair of surrogate characters.
InterpretEscapesInVerbatimString ( string source ) : string	This static method expands characters in a verbatim string, returning a modified string with character escapes replaced by the character which they denote.
Map ( int code ) : string	Map literal characters into the display form
Map ( string source ) : string
MapForCharSet ( int code ) : string	Same as Map(code) except '-' must be escaped.
OrdinalOfCharLiteral ( string source, int offset ) : int	Take the string representation of a possibly backslash- escaped character literal and return the character ordinal. Throws a StringInterpretException if character ordinal exceeds "symLimit".
QuoteMap ( int code ) : string
QuoteMap ( string source ) : string
SetUnicode ( ) : void

CodePoint ( string pattern, int &index ) : int
EscapedChar ( string source, int &index ) : int
GetHexadecimalChar ( string str ) : int
GetOctalChar ( string str ) : int	Assert: special case of '\0' is already filtered out.

Method Details

Canonicalize() public static method

Take a possibly escaped character literal and convert it to a canonical form. Thus @"'\377'", @"'\xff'" and @"'\u00FF'" all return @"'\xFF'". Throws a StringInterpretException if character ordinal exceeds "symLimit".

public static Canonicalize ( string source, int startIndex ) : string
source	string
startIndex	int
return	string

InterpretCharacterEscapes() public static method

This static method expands characters in a literal string, returning a modified string with character escapes replaced by the character which they denote. This includes characters outside the BMP which return a pair of surrogate characters.

public static InterpretCharacterEscapes ( string source ) : string
source	string
return	string

InterpretEscapesInVerbatimString() public static method

This static method expands characters in a verbatim string, returning a modified string with character escapes replaced by the character which they denote.

public static InterpretEscapesInVerbatimString ( string source ) : string
source	string
return	string

Map() public static method

public static Map ( int code ) : string
code	int
return	string

Map() public static method

public static Map ( string source ) : string
source	string
return	string

MapForCharSet() public static method

Same as Map(code) except '-' must be escaped.

public static MapForCharSet ( int code ) : string
code	int	Unicode codepoint
return	string

OrdinalOfCharLiteral() public static method

Take the string representation of a possibly backslash- escaped character literal and return the character ordinal. Throws a StringInterpretException if character ordinal exceeds "symLimit".
