The Parle\RParser class

(PECL parle >= 0.7.0)

Introduction

Parser class. Rules can be defined on the fly. Once finalized, a Parle\RLexer instance is required to deliver the token stream.

Parle\RParser {

/* Constants */

const integer ACTION_REDUCE = 2 ;

const integer ACTION_GOTO = 3 ;

const integer ACTION_ACCEPT = 4 ;

const integer ERROR_SYNTAX = 0 ;

const integer ERROR_NON_ASSOCIATIVE = 1 ;

const integer ERROR_UNKOWN_TOKEN = 2 ;

action: Current parser action that matches one of the action class constants, readonly.
reduceId: Grammar rule id just processed in the reduce action. The value corresponds either to a token or to a production id. Readonly.
