◆ GetAlignedPointerFromInternalField() [3/3]

void * v8::Object::GetAlignedPointerFromInternalField ( int  index)
inline

Gets a 2-byte-aligned native pointer from an internal field. This field must have been set by SetAlignedPointerInInternalField, everything else leads to undefined behavior.

Local<String> v8::Object::GetConstructorName ( )

Returns the name of the function invoked as a constructor for this object.

◆ GetIdentityHash()

◆ GetInternalField()

Local< Value > v8::Object::GetInternalField ( int  index)
inline

Gets the value from an internal field.

Here is the call graph for this function:

◆ GetIsolate()

Isolate* v8::Object::GetIsolate ( )

◆ GetOwnPropertyNames() [1/2]

MaybeLocal<Array> v8::Object::GetOwnPropertyNames ( Local< Context context)

This function has the same functionality as GetPropertyNames but the returned array doesn't contain the names of properties from prototype objects.

◆ GetOwnPropertyNames() [2/2]

MaybeLocal<Array> v8::Object::GetOwnPropertyNames ( Local< Context context,
PropertyFilter  filter,
KeyConversionMode  key_conversion = KeyConversionMode::kKeepNumbers 
)

Returns an array containing the names of the filtered properties of this object, including properties from prototype objects. The array returned by this method contains the same values as would be enumerated by a for-in statement over this object.

◆ GetPrivate()

MaybeLocal<Value> v8::Object::GetPrivate ( Local< Context context,
Local< Private key 
)

◆ GetPropertyAttributes()

Maybe<PropertyAttribute> v8::Object::GetPropertyAttributes ( Local< Context context,
Local< Value key 
)

◆ GetPropertyNames() [1/2]

MaybeLocal<Array> v8::Object::GetPropertyNames ( Local< Context context)

Returns an array containing the names of the enumerable properties of this object, including properties from prototype objects. The array returned by this method contains the same values as would be enumerated by a for-in statement over this object.

◆ GetPropertyNames() [2/2]

MaybeLocal<Array> v8::Object::GetPropertyNames ( Local< Context context,
KeyCollectionMode  mode,
PropertyFilter  property_filter,
IndexFilter  index_filter,
KeyConversionMode  key_conversion = KeyConversionMode::kKeepNumbers 
)

◆ GetPrototype()

Local<Value> v8::Object::GetPrototype ( )

Get the prototype object. This does not skip objects marked to be skipped by proto and it does not consult the security handler.

◆ GetRealNamedProperty()

MaybeLocal<Value> v8::Object::GetRealNamedProperty ( Local< Context context,
Local< Name key 
)

If result.IsEmpty() no real property was located on the object or in the prototype chain. This means interceptors in the prototype chain are not called.

◆ GetRealNamedPropertyAttributes()

Maybe<PropertyAttribute> v8::Object::GetRealNamedPropertyAttributes ( Local< Context context,
Local< Name key 
)

Gets the property attributes of a real property which can be None or any combination of ReadOnly, DontEnum and DontDelete. Interceptors in the prototype chain are not called.

◆ GetRealNamedPropertyAttributesInPrototypeChain()

Maybe<PropertyAttribute> v8::Object::GetRealNamedPropertyAttributesInPrototypeChain ( Local< Context context,
Local< Name key 
)

Gets the property attributes of a real property in the prototype chain, which can be None or any combination of ReadOnly, DontEnum and DontDelete. Interceptors in the prototype chain are not called.

◆ GetRealNamedPropertyInPrototypeChain()

MaybeLocal<Value> v8::Object::GetRealNamedPropertyInPrototypeChain ( Local< Context context,
Local< Name key 
)

If result.IsEmpty() no real property was located in the prototype chain. This means interceptors in the prototype chain are not called.

◆ Has() [1/2]

Maybe<bool> v8::Object::Has ( Local< Context context,
Local< Value key 
)

Object::Has() calls the abstract operation HasProperty(O, P) described in ECMA-262, 7.3.10. Has() returns true, if the object has the property, either own or on the prototype chain. Interceptors, i.e., PropertyQueryCallbacks, are called if present.

Has() has the same side effects as JavaScript's variable in object. For example, calling Has() on a revoked proxy will throw an exception.

Note
Has() converts the key to a name, which possibly calls back into JavaScript.

See also v8::Object::HasOwnProperty() and v8::Object::HasRealNamedProperty().

◆ Has() [2/2]

Maybe<bool> v8::Object::Has ( Local< Context context,
uint32_t  index 
)

◆ HasIndexedLookupInterceptor()

bool v8::Object::HasIndexedLookupInterceptor ( )

Tests for an index lookup interceptor.

◆ HasNamedLookupInterceptor()

bool v8::Object::HasNamedLookupInterceptor ( )

Tests for a named lookup interceptor.

◆ HasOwnProperty() [1/2]

Maybe<bool> v8::Object::HasOwnProperty ( Local< Context context,
Local< Name key 
)

HasOwnProperty() is like JavaScript's Object.prototype.hasOwnProperty().

See also v8::Object::Has() and v8::Object::HasRealNamedProperty().

◆ HasOwnProperty() [2/2]

Maybe<bool> v8::Object::HasOwnProperty ( Local< Context context,
uint32_t  index 
)

◆ HasPrivate()

Maybe<bool> v8::Object::HasPrivate ( Local< Context context,
Local< Private key 
)

Functionality for private properties. This is an experimental feature, use at your own risk. Note: Private properties are not inherited. Do not rely on this, since it may change.

◆ HasRealIndexedProperty()

Maybe<bool> v8::Object::HasRealIndexedProperty ( Local< Context context,
uint32_t  index 
)

◆ HasRealNamedCallbackProperty()

Maybe<bool> v8::Object::HasRealNamedCallbackProperty ( Local< Context context,
Local< Name key 
)

◆ HasRealNamedProperty()

Maybe<bool> v8::Object::HasRealNamedProperty ( Local< Context context,
Local< Name key 
)

Use HasRealNamedProperty() if you want to check if an object has an own property without causing side effects, i.e., without calling interceptors.

This function is similar to v8::Object::HasOwnProperty(), but it does not call interceptors.

Note
Consider using non-masking interceptors, i.e., the interceptors are not called if the receiver has the real named property. See v8::PropertyHandlerFlags::kNonMasking.

See also v8::Object::Has().

◆ InternalFieldCount() [1/3]

int v8::Object::InternalFieldCount ( )

Gets the number of internal fields for this Object.

◆ InternalFieldCount() [2/3]

static int v8::Object::InternalFieldCount ( const BasicTracedReference< Object > &  object)
inlinestatic

Same as above, but works for BasicTracedReference.

◆ InternalFieldCount() [3/3]

static int v8::Object::InternalFieldCount ( const PersistentBase< Object > &  object)
inlinestatic

Same as above, but works for PersistentBase.

◆ IsApiWrapper()

bool v8::Object::IsApiWrapper ( )

True if this object can carry information relevant to the embedder in its embedder fields, false otherwise. This is generally true for objects constructed through function templates but also holds for other types where V8 automatically adds internal fields at compile time, such as e.g. v8::ArrayBuffer.

◆ IsCallable()

bool v8::Object::IsCallable ( )

Checks whether a callback is set by the ObjectTemplate::SetCallAsFunctionHandler method. When an Object is callable this method returns true.

◆ IsCodeLike()

bool v8::Object::IsCodeLike ( Isolate isolate)

Support for TC39 "dynamic code brand checks" proposal.

This API allows to query whether an object was constructed from a "code like" ObjectTemplate.

See also: v8::ObjectTemplate::SetCodeLike

◆ IsConstructor()

bool v8::Object::IsConstructor ( )

True if this object is a constructor.

◆ IsUndetectable()

bool v8::Object::IsUndetectable ( )

True if this object was created from an object template which was marked as undetectable. See v8::ObjectTemplate::MarkAsUndetectable for more information.

◆ New() [1/2]

static Local<Object> v8::Object::New ( Isolate isolate)
static

◆ New() [2/2]

static Local<Object> v8::Object::New ( Isolate isolate,
Local< Value prototype_or_null,
Local< Name > *  names,
Local< Value > *  values,
size_t  length 
)
static

Creates a JavaScript object with the given properties, and a the given prototype_or_null (which can be any JavaScript value, and if it's null, the newly created object won't have a prototype at all). This is similar to Object.create(). All properties will be created as enumerable, configurable and writable properties.

◆ ObjectProtoToString()

MaybeLocal<String> v8::Object::ObjectProtoToString ( Local< Context context)

Call builtin Object.prototype.toString on this object. This is different from Value::ToString() that may call user-defined toString function. This one does not.

◆ PreviewEntries()

MaybeLocal<Array> v8::Object::PreviewEntries ( bool *  is_key_value)

If this object is a Set, Map, WeakSet or WeakMap, this returns a representation of the elements of this object as an array. If this object is a SetIterator or MapIterator, this returns all elements of the underlying collection, starting at the iterator's current position. For other types, this will return an empty MaybeLocal<Array> (without scheduling an exception).

◆ Set() [1/2]

Maybe<bool> v8::Object::Set ( Local< Context context,
Local< Value key,
Local< Value value 
)

Set only return Just(true) or Empty(), so if it should never fail, use result.Check().

◆ Set() [2/2]

Maybe<bool> v8::Object::Set ( Local< Context context,
uint32_t  index,
Local< Value value 
)

◆ SetAccessor()

Maybe<bool> v8::Object::SetAccessor ( Local< Context context,
Local< Name name,
AccessorNameGetterCallback  getter,
AccessorNameSetterCallback  setter = nullptr,
MaybeLocal< Value data = MaybeLocalValue >(),
AccessControl  settings = DEFAULT,
PropertyAttribute  attribute = None,
SideEffectType  getter_side_effect_type = SideEffectType::kHasSideEffect,
SideEffectType  setter_side_effect_type = SideEffectType::kHasSideEffect 
)

Note: SideEffectType affects the getter only, not the setter.

◆ SetAccessorProperty()

void v8::Object::SetAccessorProperty ( Local< Name name,
Local< Function getter,
Local< Function setter = LocalFunction >(),
PropertyAttribute  attribute = None,
AccessControl  settings = DEFAULT 
)

◆ SetAlignedPointerInInternalField()

void v8::Object::SetAlignedPointerInInternalField ( int  index,
void *  value 
)

Sets a 2-byte-aligned native pointer in an internal field. To retrieve such a field, GetAlignedPointerFromInternalField must be used, everything else leads to undefined behavior.

◆ SetAlignedPointerInInternalFields()

void v8::Object::SetAlignedPointerInInternalFields ( int  argc,
int  indices[],
void *  values[] 
)

◆ SetIntegrityLevel()

Maybe<bool> v8::Object::SetIntegrityLevel ( Local< Context context,
IntegrityLevel  level 
)

Sets the integrity level of the object.

◆ SetInternalField()

void v8::Object::SetInternalField ( int  index,
Local< Value value 
)

Sets the value in an internal field.

◆ SetLazyDataProperty()

Maybe<bool> v8::Object::SetLazyDataProperty ( Local< Context context,
Local< Name name,
AccessorNameGetterCallback  getter,
Local< Value data = LocalValue >(),
PropertyAttribute  attributes = None,
SideEffectType  getter_side_effect_type = SideEffectType::kHasSideEffect,
SideEffectType  setter_side_effect_type = SideEffectType::kHasSideEffect 
)

Attempts to create a property with the given name which behaves like a data property, except that the provided getter is invoked (and provided with the data value) to supply its value the first time it is read. After the property is accessed once, it is replaced with an ordinary data property.

Analogous to Template::SetLazyDataProperty.

◆ SetNativeDataProperty()

Maybe<bool> v8::Object::SetNativeDataProperty ( Local< Context context,
Local< Name name,
AccessorNameGetterCallback  getter,
AccessorNameSetterCallback  setter = nullptr,
Local< Value data = LocalValue >(),
PropertyAttribute  attributes = None,
SideEffectType  getter_side_effect_type = SideEffectType::kHasSideEffect,
SideEffectType  setter_side_effect_type = SideEffectType::kHasSideEffect 
)

Sets a native data property like Template::SetNativeDataProperty, but this method sets on this object directly.

◆ SetPrivate()

Maybe<bool> v8::Object::SetPrivate ( Local< Context context,
Local< Private key,
Local< Value value 
)

◆ SetPrototype()

Maybe<bool> v8::Object::SetPrototype ( Local< Context context,
Local< Value prototype 
)

Set the prototype object. This does not skip objects marked to be skipped by proto and it does not consult the security handler.
