isJSSlowArray

public static boolean isJSSlowArray(JSDynamicObject obj)

getClassName

public com.oracle.truffle.api.strings.TruffleString getClassName(JSDynamicObject object)

Description copied from class: JSClass

The [[Class]] internal property. For ES5, this is the second part of what Object.prototype.toString.call(myObj) returns, e.g. "[object Array]".

Specified by:

getClassName in class JSClass

Parameters:

object - object to be used

getOwnHelper

public Object getOwnHelper(JSDynamicObject store,
                           Object thisObj,
                           long index,
                           com.oracle.truffle.api.nodes.Node encapsulatingNode)

Description copied from class: JSNonProxy

Like getOwnProperty, but returns null if value is not present instead of undefined.

Overrides:

getOwnHelper in class JSAbstractArray

set

public boolean set(JSDynamicObject thisObj,
                   long index,
                   Object value,

                   boolean isStrict,
                   com.oracle.truffle.api.nodes.Node encapsulatingNode)

Overrides:

set in class JSAbstractArray

delete

public boolean delete(JSDynamicObject thisObj,
                      long index,
                      boolean isStrict)

Overrides:

delete in class JSAbstractArray

makeSlowArray

protected JSDynamicObject makeSlowArray(JSDynamicObject thisObj)

Overrides:

makeSlowArray in class JSAbstractArray

defineOwnPropertyIndex

protected boolean defineOwnPropertyIndex(JSDynamicObject thisObj,
                                         com.oracle.truffle.api.strings.TruffleString name,

                                         boolean doThrow)

Implements part "3" of 15.4.5.1 [[DefineOwnProperty]], redefining one of the index property of an Array.

Overrides:

defineOwnPropertyIndex in class JSAbstractArray

Returns:

whether the operation was successful

setLength

public boolean setLength(JSDynamicObject thisObj,
                         long length,
                         boolean doThrow)

Overrides:
