getCompiledRegex

getGroupsFactory

public static JSObjectFactory getGroupsFactory(com.oracle.truffle.api.object.DynamicObject thisObj)

getRealm

public static Object getRealm(com.oracle.truffle.api.object.DynamicObject thisObj)

create

public static com.oracle.truffle.api.object.DynamicObject create(JSContext ctx,

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.
