Member Data Documentation

◆ expect

QList<Cat> DynGenPar::NextTokenConstraints::expect

list of context-free categories the next token MUST match

The categories in this list may be nonterminals or tokens. But they MUST be context-free. In other words, they must not be PMCFG pseudo-categories, and none of the rules used to derive them may contain any PMCFG pseudo-categories or next token constraints. (In particular, it is not possible to nest next token constraints.)

◆ taboo

QList<Cat> DynGenPar::NextTokenConstraints::taboo

list of context-free categories the next token MUST NOT match

The categories in this list may be nonterminals or tokens. But they MUST be context-free. In other words, they must not be PMCFG pseudo-categories, and none of the rules used to derive them may contain any PMCFG pseudo-categories or next token constraints. (In particular, it is not possible to nest next token constraints.)
