Thank you all for your replies.
But my intention is different. Let me be more specific:
I want others to debug the JavaScript code but not the c++ part. They will
use chrome devtools to do that. So, when they encounter any c++ object that
is made available to Javascript, I would like to display some custom
information about it.
While wrapping the object, I implimented *GenericNamedPropertyGetterCallback
*and called *SetHandler* to set it to the *ObjectTemplate* using function
*NamedPropertyHandlerConfiguration*
point_object_template->SetHandler(
v8::NamedPropertyHandlerConfiguration(AccessorGetterCallbackFunction,0,
NamedPropertyQueryCallbackFunction));
The function is implemented as follows:
void AccessorGetterCallbackFunction(v8::Local<v8::Name> property, const v8::
PropertyCallbackInfo<v8::Value>& info)
{
auto pointPtr = UnwrapPoint(info.Holder());
bool bIsString = property->IsString();
std::string accessed_property;
auto value = v8::Local<v8::String>::Cast(property);
v8::String::Utf8Value utf8_value(v8::Local<v8::String>::Cast(property));
accessed_property = *utf8_value;
if (accessed_property == "x")
info.GetReturnValue().Set(v8::Integer::New(info.GetIsolate(), pointPtr->x_
));
else if (accessed_property == "y")
info.GetReturnValue().Set(v8::Integer::New(info.GetIsolate(), pointPtr->y_
));
}
The content of p is coming as {} as shown below.

Are there any callbacks are available to set the content that is displayed
as value of p? Also, other than x and y, which are members of *Point, *another
property named *splice* is showing up. When is this property accessed?
Please let me know if you have any information.
regards,
Anoop R. S.
