Detailed Description

template<typename T>
class v8::PropertyCallbackInfo< T >

The information passed to a property callback about the context of the property access.

Examples

process.cc.

Member Function Documentation

Data()

template<typename T >

Local< Value > v8::PropertyCallbackInfo< T >::Data

inline

Returns

The data set in the configuration, i.e., in NamedPropertyHandlerConfiguration or IndexedPropertyHandlerConfiguration.

GetIsolate()

template<typename T >

Isolate * v8::PropertyCallbackInfo< T >::GetIsolate

inline

Returns

The isolate of the property access.

GetReturnValue()

template<typename T >

ReturnValue< T > v8::PropertyCallbackInfo< T >::GetReturnValue

inline

Returns

The return value of the callback. Can be changed by calling Set().

info.GetReturnValue().Set(...)

HolderV2()

template<typename T >

Local< Object > v8::PropertyCallbackInfo< T >::HolderV2

inline

Returns

The object in the prototype chain of the receiver that has the interceptor. Suppose you have x and its prototype is y, and y has an interceptor. Then info.This() is x and info.Holder() is y. In case the property is installed on the global object the Holder() would return the global proxy. TODO(http://crbug.com/333672197): rename back to Holder().

ShouldThrowOnError()

template<typename T >

bool v8::PropertyCallbackInfo< T >::ShouldThrowOnError

inline

For [[Set]], [[DefineOwnProperty]] and [[Delete]] operations (i.e. for setter/definer/deleter callbacks) indicates whether TypeError should be thrown upon operation failure. The callback should throw TypeError only if it's necessary to provide more details than a default error thrown by V8 contains in this case.

Returns

True if the intercepted function should throw if an error occurs. Usually, true corresponds to ‘'use strict’` execution mode.

Note

Always false when the operation was initiated by respecive Reflect call (i.e. Reflect.set(), Reflect.defineProperty() and Reflect.deleteProperty()).
