public class SLR1_Grammar
extends LR0_Grammar

This class implements an SLR(1) parser around a Grammar. The parser adapts to changes in the underlying Grammar. Semantics in a phrase are evaluated during a bottom-up parse, from left to right after all subtrees rooted in the phrase have been constructed. Attributes throughout the phrase are available during evaluation. SLR(1) parsing is more space- and time-efficient than LR(1) parsing; however, SLR(1) parsing is more easily confused than LR(1) parsing, since it considers lookahead terminals generally following a nonterminal (rather than specifically following it in a context) to choose between applicable phrases.
