Methods

createDataPropertyOrThrow(String name, JSValue value) → void

CreateDataPropertyOrThrow (ES6) - Used by Array.from Attempts to create or update a data property Throws TypeError if it fails

inherited

defineConstructorProperty(JSValue constructor) → void

Defines the standard prototype constructor property.

inherited

defineGetter(String name, JSFunction getter, {bool enumerable = false, JSSymbol? symbol}) → void

Define a getter for a property Defines a getter for a property. enumerable defaults to false for Object.defineProperty compatibility, but should be true for object literal getters per ES6 spec.

inherited

defineProperty(String name, PropertyDescriptor descriptor) → void

Define a property with a complete descriptor (Object.defineProperty)

inherited

defineSetter(String name, JSFunction setter, {bool enumerable = false, JSSymbol? symbol}) → void

Defines a setter for a property. enumerable defaults to false for Object.defineProperty compatibility, but should be true for object literal setters per ES6 spec.

inherited

deleteProperty(String name) → bool

Supprime a property

inherited

equals(JSValue other) → bool

Comparison operations

inherited

getAccessorDescriptor(String name) → PropertyDescriptor?

Obtient le descriptor d'un accessor sans l'appeler

inherited

getForInPropertyNames() → List<String>

Obtient les noms de propertes pour les boucles for-in Ordre selon la specification ES2015+: numeriques d'abord (tries), puis strings (ordre d'insertion)

inherited

getInternalSlot(String name) → dynamic

Get an internal slot value

inherited

getIterator() → JSIterator?

Available on JSObject, provided by the JSIterableExtension extension

Gets the iterator for this object

getOwnPropertyDescriptor(String name) → PropertyDescriptor?

Get the descriptor of a property (Object.getOwnPropertyDescriptor)

inherited

getOwnPropertyDirect(String name) → JSValue?

Obtient a property propre (sans recherche dans la chaine de prototypes) Utilise par ES2020 matchAll pour acceder aux propertes personnalisees d'arrays

inherited

getProperty(String name) → JSValue

Get a property

inherited

getPropertyBySymbol(JSSymbol symbol) → JSValue

ES6: Gets a property value using a symbol key

inherited

getPropertyNames({bool enumerableOnly = false}) → List<String>

Obtient all cles de propertes

inherited

getPrototype() → JSObject?

Obtient le prototype de cet objet

inherited

getSymbolKeys() → Iterable<JSSymbol>

ES6: Returns all symbol keys tracked on this object (not including prototype chain) Used by Object.getOwnPropertySymbols()

inherited

hasAccessorProperty(String name) → bool

Verifie si a property est un accessor (getter/setter)

inherited

hasInternalSlot(String name) → bool

Check if an internal slot exists

inherited

hasOwnProperty(String name) → bool

Verifie si a property existe dans les propertes propres (pas la chaine de prototypes)

inherited

hasProperty(String name) → bool

Verifie si a property existe (heritee ou non)

inherited

makeIterable(JSIterator iteratorFactory()) → void

Available on JSObject, provided by the JSIterableExtension extension

Add Symbol.iterator to an object

markAsArgumentsObject() → void

Marks this object as an arguments object for strict property access handling

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

registerSymbolKey(String propertyKey, JSSymbol symbol) → void

Register a symbol key for tracking (used when defineProperty is called with a symbol key)

inherited

setInternalSlot(String name, dynamic value) → void

Set an internal slot value

inherited

setProperty(String name, JSValue value) → void

Define a property

inherited

setPropertyWithSymbol(String stringKey, JSValue value, JSSymbol symbol) → void

ES6: Sets a property with a symbol key and tracks the symbol

inherited

setPrototype(JSObject? prototype) → void

Definit le prototype de cet objet

inherited

strictEquals(JSValue other) → bool

inherited

toBoolean() → bool

JavaScript type conversions (coercion)

inherited

toMap() → Map<String, dynamic>

Convertit le JSObject en Map Dart pour un acces facile aux propertes Cela evite les multiples appels a getProperty() dans les tests
