Detailed Description

An ObjectTemplate is used to create objects at runtime.

Properties added to an ObjectTemplate are added to each object created from the ObjectTemplate.

Examples: process.cc.

Member Function Documentation

◆ Cast()

ObjectTemplate * v8::ObjectTemplate::Cast ( Data * data )

inlinestatic

◆ InternalFieldCount()

int v8::ObjectTemplate::InternalFieldCount ( ) const

Gets the number of internal fields for objects generated from this template.

◆ IsCodeLike()

bool v8::ObjectTemplate::IsCodeLike ( ) const

◆ IsImmutableProto()

bool v8::ObjectTemplate::IsImmutableProto ( ) const

Returns true if the object will be an immutable prototype exotic object.

◆ MarkAsUndetectable()

void v8::ObjectTemplate::MarkAsUndetectable ( )

Mark object instances of the template as undetectable.

In many ways, undetectable objects behave as though they are not there. They behave like 'undefined' in conditionals and when printed. However, properties can be accessed and called as on normal objects.

◆ New()

static Local< ObjectTemplate > v8::ObjectTemplate::New	(	Isolate *	isolate,
		Local< FunctionTemplate >	constructor = `Local< FunctionTemplate >()`
	)

static

Creates an ObjectTemplate.

Examples: shell.cc.

◆ NewInstance()

MaybeLocal< Object > v8::ObjectTemplate::NewInstance ( Local< Context > context )

Creates a new instance of this template.

Parameters

context The context in which the instance is created.

◆ SealAndPrepareForPromotionToReadOnly()

void v8::ObjectTemplate::SealAndPrepareForPromotionToReadOnly ( )

Seal the object and mark it for promotion to read only space during context snapshot creation.

This is an experimental feature and may still change significantly.

◆ SetAccessCheckCallback()

void v8::ObjectTemplate::SetAccessCheckCallback	(	AccessCheckCallback	callback,
		Local< Value >	data = `Local< Value >()`
	)

Sets access check callback on the object template and enables access checks.

When accessing properties on instances of this object template, the access check callback will be called to determine whether or not to allow cross-context access to the properties.

◆ SetAccessCheckCallbackAndHandler()

void v8::ObjectTemplate::SetAccessCheckCallbackAndHandler	(	AccessCheckCallback	callback,
		const NamedPropertyHandlerConfiguration &	named_handler,
		const IndexedPropertyHandlerConfiguration &	indexed_handler,
		Local< Value >	data = `Local< Value >()`
	)

Like SetAccessCheckCallback but invokes an interceptor on failed access checks instead of looking up all-can-read properties. You can only use either this method or SetAccessCheckCallback, but not both at the same time.

◆ SetCallAsFunctionHandler()

void v8::ObjectTemplate::SetCallAsFunctionHandler	(	FunctionCallback	callback,
		Local< Value >	data = `Local< Value >()`
	)

Sets the callback to be used when calling instances created from this template as a function. If no callback is set, instances behave like normal JavaScript objects that cannot be called as a function.

◆ SetCodeLike()

void v8::ObjectTemplate::SetCodeLike ( )

Support for TC39 "dynamic code brand checks" proposal.

This API allows to mark (& query) objects as "code like", which causes them to be treated like Strings in the context of eval and function constructor.

Reference: https://github.com/tc39/proposal-dynamic-code-brand-checks

◆ SetHandler() [1/2]

void v8::ObjectTemplate::SetHandler ( const IndexedPropertyHandlerConfiguration & configuration )

Sets an indexed property handler on the object template.

Whenever an indexed property is accessed on objects created from this object template, the provided callback is invoked instead of accessing the property directly on the JavaScript object.

Parameters

configuration The IndexedPropertyHandlerConfiguration that defines the callbacks to invoke when accessing a property.

◆ SetHandler() [2/2]

void v8::ObjectTemplate::SetHandler ( const NamedPropertyHandlerConfiguration & configuration )

Sets a named property handler on the object template.

Whenever a property whose name is a string or a symbol is accessed on objects created from this object template, the provided callback is invoked instead of accessing the property directly on the JavaScript object.

Parameters

configuration The NamedPropertyHandlerConfiguration that defines the callbacks to invoke when accessing a property.

◆ SetImmutableProto()

void v8::ObjectTemplate::SetImmutableProto ( )

Makes the ObjectTemplate for an immutable prototype exotic object, with an immutable proto.

◆ SetInternalFieldCount()

void v8::ObjectTemplate::SetInternalFieldCount ( int value )

Sets the number of internal fields for objects generated from this template.
