Class RoseParser

java.lang.Object
  org.eclipse.emf.importer.rose.parser.RoseParser

public class RoseParser
extends java.lang.Object

A parser for Rose files. This parser uses the following contex-free grammar:

   E  -> ( O )  |  ( L )  |  ( V )  |   S'  ;expression
   S' -> S  |  "|" S'                       ;sequence of strings
   S" -> EPS | S' S"                        ;sequence of strings inside list
   O  -> object S P'                        ;object
   V  -> value S S'                         ;value
   P' -> EPS  |  P P'                       ;sequence of pairs
   P  -> K E                                ;pair
   L  -> list S O' | list S S"              ;list
   O' -> EPS  |  ( O ) O'                   ;sequence of objects
 

Here are the terminals:

   K      is a key token (always one word)
   S      is a string token (can have multiple words)
   object is an object token
   list   is a list token
   "|"    is a vertical bar token
   EPS    is an empty string token
