Method Details

AddCustomConstant() public static method

Adds a custom constant to the parser (to the primary context).

public static AddCustomConstant ( this parser, String name, Double constant ) : void
parser	this	The parser to extend.
name	String	/// The name of the symbol corresponding to the constant. ///
constant	Double	/// The value of the constant. ///
return	void

AddCustomConstant() public static method

Adds a custom constant to the parser (to the primary context).

public static AddCustomConstant ( this parser, String name, Value constant ) : void
parser	this	The parser to extend.
name	String	/// The name of the symbol corresponding to the constant. ///
constant	Value	/// The value of the constant. ///
return	void

AddCustomFunction() public static method

Adds a custom function to be used by the parser (to the primary context).

public static AddCustomFunction ( this parser, String name, FunctionDelegate f ) : void
parser	this	The parser to extend.
name	String	/// The name of the symbol corresponding to the function that should be added. ///
f	FunctionDelegate	/// The function that fulfills the signature Value f(Value v). ///
