Method Details

getCompiledRegex

public static Object getCompiledRegex(JSRegExpObject thisObj)

getGroupsFactory

public static JSObjectFactory getGroupsFactory(JSRegExpObject thisObj)

getRealm

public static Object getRealm(JSRegExpObject thisObj)

getLegacyFeaturesEnabled

public static boolean getLegacyFeaturesEnabled(JSRegExpObject 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.

create

public static JSRegExpObject create(JSContext context,
 JSRealm realm,
 Object compiledRegex,
 JSObjectFactory groupsFactory)

Creates a new JavaScript RegExp object without a lastIndex property.

create

public static JSRegExpObject create(JSContext context,
 JSRealm realm,
 JSDynamicObject proto,
 Object compiledRegex,
 JSObjectFactory groupsFactory,
 boolean legacyFeaturesEnabled)

Creates a new JavaScript RegExp object without a lastIndex property.

create

public static JSRegExpObject create(JSContext context,
 JSRealm realm,
 Object compiledRegex,
 JSObjectFactory groupsFactory,
 boolean legacyFeaturesEnabled)

Creates a new JavaScript RegExp object without a lastIndex property.

updateCompilation

public static void updateCompilation(JSContext ctx,
 JSRegExpObject thisObj,
 Object regex)

createGroupsObject

public static JSDynamicObject createGroupsObject(JSRealm realm,
 JSObjectFactory groupsFactory,
 Object regexResult,
 com.oracle.truffle.api.strings.TruffleString input,
 boolean isIndices)

buildGroupsFactory

public static JSObjectFactory buildGroupsFactory(JSContext ctx,
 Object namedCaptureGroups)

prototypeToString

public static com.oracle.truffle.api.strings.TruffleString prototypeToString(JSRegExpObject thisObj)

Format: '/' pattern '/' flags. Flags may be none, one, or more of 'dgimsuy', in that order.

Example: /ab*c/gi

isJSRegExp

public static boolean isJSRegExp(Object obj)

createPrototype

public JSDynamicObject createPrototype(JSRealm realm,
 JSFunctionObject ctor)

Specified by:

createPrototype in interface JSConstructorFactory

makeInitialShape

getIntrinsicDefaultProto

public JSDynamicObject getIntrinsicDefaultProto(JSRealm realm)

Description copied from class: JSClass

Allows invokevirtual of this method instead of invokeinterface. Classes overriding this method should implement PrototypeSupplier.
