Detailed Description

Parse string as an equation. This class expects a string that contains the same string representation that is generated by the Node class in infix notation.

Constructor & Destructor Documentation

Parser::Parser ( const string &  expr, Equation &  eqn  )

inline

Constructor for Parser class.

Parameters

expr	String containing equation.
eqn	Equation object container for node tree.

Member Function Documentation

Equation& Parser::getEqn ( )

inline

Get reference to Equation object.

Returns

Equation object reference.

bool Parser::match

(

const string &

s

)

Returns

True if string is matched.

char Parser::next

(

)

Get next character in string and advance pointer.

Returns

Next character.

char Parser::peek ( )

inline

Get the next character to be parsed without advancing.
