getCompiledRegex

getGroupsFactory

public static JSObjectFactory getGroupsFactory(JSDynamicObject thisObj)

getRealm

public static Object getRealm(JSDynamicObject thisObj)

create

public static JSRegExpObject create(JSContext ctx,
                                    JSRealm realm,
                                    Object compiledRegex)

Creates a new JavaScript RegExp object (with a lastIndex of 0).

This overload incurs hitting a CompilerDirectives.TruffleBoundary when having to examine the compiledRegex for information about named capture groups. In order to avoid a CompilerDirectives.TruffleBoundary in cases when your regular expression has no named capture groups, consider using the com.oracle.truffle.js.nodes.intl.CreateRegExpNode.
