Object sent to grammar rule
Description
This class is a wrapper around the objects actually passed to each
grammar rule. Index lookup and assignment actually assign the
.value attribute of the underlying YaccSymbol object.
The lineno() method returns the line number of a given
item (or 0 if not defined). The linespan() method returns
a tuple of (startline,endline) representing the range of lines
for a symbol. The lexspan() method returns a tuple (lexpos,endlexpos)
representing the range of positional information for a symbol.
Usage
YaccProduction
Format
An R6Class generator object
