Type Members

  1. implicit final class EnhancedLogicalPlan extends AnyVal

    Some syntactic sugar which makes it easier to work with optional clauses for LogicalPlans.

  10. def checkDuplicateKeys[T](keyPairs: Seq[(String, T)], ctx: ParserRuleContext): Unit

    Check if duplicate keys exist in a set of key-value pairs.

  12. def command(ctx: ParserRuleContext): String

    Get the command which created the token.

  13. def entry(key: String, value: Token): Seq[(String, String)]

    Collect the entries if any.

  20. def interval(start: Token, end: Token): String

    Get all the text which between the given start and end tokens.

    Get all the text which between the given start and end tokens. When we need to extract everything between two tokens including all spaces we should use this method instead of defined a named Antlr4 rule for .*?, which somehow parse "a b" -> "ab" in some cases

  25. def operationNotAllowed(message: String, ctx: ParserRuleContext): Nothing
  26. def position(token: Token): Origin

    Get the origin (line and position) of the token.

  27. val qualifiedEscapedIdentifier: Regex

    the column name pattern in quoted regex with qualifier

  28. def remainder(token: Token): String

    Get all the text which comes after the given token.

  29. def remainder(ctx: ParserRuleContext): String

    Get all the text which comes after the given rule.

  30. def source(ctx: ParserRuleContext): String

    Get the code that creates the given node.

  31. def string(node: TerminalNode): String

    Convert a string node into a string.

  32. def string(token: Token): String

    Convert a string token into a string.

  33. def stringWithoutUnescape(node: TerminalNode): String

    Convert a string node into a string without unescaping.

    AnyRef
  35. def toString(): String
    Definition Classes
    AnyRef → Any
  36. def unescapeSQLString(b: String): String

    Unescape backslash-escaped string enclosed by quotes.

  37. def validate(f: => Boolean, message: String, ctx: ParserRuleContext): Unit

    Validate the condition.

    Validate the condition. If it doesn't throw a parse exception.

    @throws(classOf[java.lang.InterruptedException])
  39. final def wait(arg0: Long, arg1: Int): Unit

  41. def withOrigin[T](ctx: ParserRuleContext)(f: => T): T

    Register the origin of the context.

    Register the origin of the context. Any TreeNode created in the closure will be assigned the registered origin. This method restores the previously set origin after completion of the closure.
