genExpr
public org.antlr.stringtemplate.StringTemplate genExpr(CodeGenerator generator, org.antlr.stringtemplate.StringTemplateGroup templates, DFA dfa)
Description copied from class:SemanticContext
Generate an expression that will evaluate the semantic context, given a set of output templates.- Specified by:
genExpr
in classSemanticContext
-
getGatedPredicateContext
public SemanticContext getGatedPredicateContext()
Description copied from class:SemanticContext
Given a semantic context expression tree, return a tree with all nongated predicates set to true and then reduced. So p&&(q||r) would return p&&r if q is nongated but p and r are gated.- Specified by:
getGatedPredicateContext
in classSemanticContext
-
isSyntacticPredicate
public boolean isSyntacticPredicate()
- Specified by:
isSyntacticPredicate
in classSemanticContext
-
trackUseOfSyntacticPredicates
public void trackUseOfSyntacticPredicates(Grammar g)
Description copied from class:SemanticContext
Notify the indicated grammar of any syn preds used within this context- Overrides:
