Package org.sbml.jsbml.math.parser

Class FormulaParser

java.lang.Object

org.sbml.jsbml.math.parser.FormulaParser

All Implemented Interfaces:

FormulaParserConstants, IFormulaParser

public class FormulaParser
extends java.lang.Object
implements IFormulaParser, FormulaParserConstants

Class used to parse infix mathematical formula and returns a representation of it as an Abstract Syntax Tree (AST).

Support almost the same syntax as defined in the LibSBML C-inspired infix notation taken from SBML Level 1 parser.

Since:

0.8
