Interface LeftRecursiveRule

All Superinterfaces:

AstNodeType, Rule

public interface LeftRecursiveRule
extends Rule

A LeftRecursiveRule must be used in place of a Rule in order to support left recursion. Indeed SSLR embeds a LL(*) parser which doesn't support by default such left recursive rule : additiveExpr.is(or(and(additiveExpr, "+", INTEGER), INTEGER)
