Return first ancestor node up the chain towards the root that has ruleName. Search includes the current node.

getAncestor

public static org.antlr.v4.runtime.ParserRuleContext getAncestor(org.antlr.v4.runtime.ParserRuleContext t,
                                                                 int ruleIndex)

Return first ancestor node up the chain towards the root that has the rule index. Search includes the current node.

getFirstAncestorOfType

public static org.antlr.v4.runtime.ParserRuleContext getFirstAncestorOfType(org.antlr.v4.runtime.ParserRuleContext t,
                                                                            Class<?> clazz)

Return first ancestor node up the chain towards the root that is clazz. Search includes the current node.
