visit

public static Object visit(Function<org.antlr.v4.runtime.tree.ParseTree,Object> visitor,
 org.antlr.v4.runtime.tree.ParseTree tree)

visitList

public static <T> List<T> visitList(org.antlr.v4.runtime.tree.ParseTreeVisitor<?> visitor,
 List<? extends org.antlr.v4.runtime.ParserRuleContext> contexts,
 Class<T> clazz)

typedParsing

public static <T> T typedParsing(org.antlr.v4.runtime.tree.ParseTreeVisitor<?> visitor,
 org.antlr.v4.runtime.tree.ParseTree ctx,
 Class<T> type)

source

public static Source source(org.antlr.v4.runtime.tree.ParseTree ctx)

source

public static Source source(org.antlr.v4.runtime.tree.TerminalNode terminalNode)

source

public static Source source(org.antlr.v4.runtime.ParserRuleContext parserRuleContext)

source

public static Source source(org.antlr.v4.runtime.Token token)

source

public static Source source(org.antlr.v4.runtime.ParserRuleContext begin,

source

public static Source source(org.antlr.v4.runtime.tree.TerminalNode begin,

source

public static Source source(org.antlr.v4.runtime.Token start,
 org.antlr.v4.runtime.Token stop)

text

public static String text(org.antlr.v4.runtime.tree.ParseTree node)

Retrieves the raw text of the node (without interpreting it as a string literal).

nameOrPosition

public static String nameOrPosition(org.antlr.v4.runtime.Token token)

Extract the name or the position of an ES|QL parameter.

promqlNameOrPosition

public static String promqlNameOrPosition(org.antlr.v4.runtime.Token token)

Extract the name or the position of a PromQL parameter. Kept separate from nameOrPosition(org.antlr.v4.runtime.Token) since the two lexers assign independent token type IDs that can collide after grammar changes.

unquoteIdString

public static String unquoteIdString(String quotedString)

quoteIdString

public static String quoteIdString(String unquotedString)

buildStats

public static ParserUtils.Stats buildStats(Source source,
 List<Expression> groupings,
 List<NamedExpression> aggregates)
