Class: Grammar Zope-2.2.1-src/lib/python/Products/ZGadflyDA/gadfly/kjParser.py

the grammar class: a grammar consists of - a LexDict lexical dictionary; - a deterministic FSMachine; - a Rulelist and optionally a dictionary that maps Rulenames to Rulelist indices (used for dumping and externally)

Methods   
AddNameDict
Addterm
Bind
CleanUp
DoParse
DoParse1
PrintDefaults
SetCaseSensitivity
__init__
  AddNameDict 
AddNameDict ( self,  RuleNameDict )

this method associates rules to names using a RuleNameDict dictionary which maps names to rule indices. after invocation self.RuleNameToIndex[ name ] gives the index in self.RuleL for the rule associated with name, and self.RuleL[index].Name gives the name associated with the rule self.RuleL[index]

  Addterm 
Addterm (
        self,
        termname,
        regexpstr,
        funct,
        )

bind a terminal to a regular expression and interp function in the lexical dictionary (convenience)

  Bind 
Bind (
        self,
        Rulename,
        NewFunction,
        )

if the Name dictionary has been initialized this method will (re)bind a reduction function to a rule associated with Rulename

  CleanUp 
CleanUp ( self )

this may be silly, but to save some space in construction a token dictionary may be used that facilitates sharing of token representations. This method either initializes the dictionary or disposes of it if it exists

  DoParse 
DoParse (
        self,
        String,
        Context=None,
        DoReductions=1,
        )

parse a string using the grammar, return result and context

  DoParse1 
DoParse1 (
        self,
        String,
        Context=None,
        DoReductions=1,
        )

parse a string using the grammar, but only return the result of the last reduction, without the context

  PrintDefaults 
PrintDefaults ( self )

look for default bindings

  SetCaseSensitivity 
SetCaseSensitivity ( self,  Boolean )

setting case sensitivity: must happen before keyword installation in LexD.

  __init__ 
__init__ (
        self,
        LexD,
        DFA,
        RuleL,
        RuleNameDict=None,
        )

Evaluate determines whether rules should be evaluated after reductions. Context is an argument passed to the list reduction function
