Public fields
LNode	Basis
	A node that contains the original code of the rule, or, if the rule was created programmatically, the method prototype (e.g. #fn(int, Rule, #(#var(int, arg))), which means int Rule(int arg)). This can be null, in which case the default prototype is void Rule();, or if the rule is a starting rule or token, public void Rule();. More...

Member Data Documentation

LNode Loyc.LLParserGenerator.Rule.Basis

A node that contains the original code of the rule, or, if the rule was created programmatically, the method prototype (e.g. #fn(int, Rule, #(#var(int, arg))), which means int Rule(int arg)). This can be null, in which case the default prototype is void Rule();, or if the rule is a starting rule or token, public void Rule();.

The Basis is also used to provide an error location.
