genExpr

public org.stringtemplate.v4.ST genExpr(CodeGenerator generator,
                                        org.stringtemplate.v4.STGroup 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 class SemanticContext

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 class SemanticContext

hasUserSemanticPredicate

public boolean hasUserSemanticPredicate()

Specified by:

hasUserSemanticPredicate in class SemanticContext

isSyntacticPredicate

public boolean isSyntacticPredicate()

Specified by:

isSyntacticPredicate in class SemanticContext

trackUseOfSyntacticPredicates

public void trackUseOfSyntacticPredicates(Grammar g)

Description copied from class: SemanticContext

Notify the indicated grammar of any syn preds used within this context

Overrides:

public boolean equals(Object object)

Overrides:

equals in class Object

hashCode
