A signature describing the syntax tree of regular expressions.

Import path

import codeql.regex.RegexTreeView

Predicates

isDotAll

Holds if root has the s flag for multi-line matching.

isEscapeClass

Holds if term is an escape class representing e.g. \d. clazz is which character class it represents, e.g. “d” for \d.

isExcluded

Holds if the regular expression should not be considered.

isIgnoreCase

Holds if root has the i flag for case-insensitive matching.

isPossessive

Holds if term is a possessive quantifier. As javascript’s regexes do not support possessive quantifiers, this never holds, but is used by the shared library.

matchesAnyPrefix

Holds if the regex that term is part of is used in a way that ignores any leading prefix of the input it’s matched against. Not yet implemented for JavaScript.

matchesAnySuffix

Holds if the regex that term is part of is used in a way that ignores any trailing suffix of the input it’s matched against. Not yet implemented for JavaScript.
