GetNextToken ( ) : Token	Get the next token and determine its value.
IsIdentifier ( string &identifier ) : bool	Determines whether the current token is an identifier and returns it.
IsIsolatedChar ( char &c ) : bool	Determine wether the current togen is an IsolatedChar and return it.
IsNumber ( double &numValue ) : bool	Determine wether the current token is a number and return it.
IsString ( string &s ) : bool	Determine wether the current token is a string and return it.
Match ( Token t ) : bool	Determine wether a token matches with the current one.
MatchIdentifier ( string identifier ) : bool	Determine wether a string is the wanted identifier.
MatchIsolatedChar ( char c ) : bool	Determine wether a char is the wanted IsolatedChar.

public CommandParser ( string s ) : System
s	string	The string to parse.
return	System

CommandParser() public method

Initializes a new instance of the CommandParser class. Create a parser object from a string. It initialize the parsing at the index selected by the user.

public CommandParser ( string s, int startIndex ) : System
s	string	The string to parse.
startIndex	int	Index of the first character for parsing.
return	System

GetNextToken() public method

Get the next token and determine its value.

public GetNextToken ( ) : Token
return	Token

IsIdentifier() public method

Determines whether the current token is an identifier and returns it.

public IsIdentifier ( string &identifier ) : bool
identifier	string	Out : the identifier value.
