Hi,
How can I change (and dispose) an object allocate with External::New ?
Assuming I have the following code:
SessionBridge* session_ptr = new SessionBridge(session);
//create a pointer to a class template
Handle<FunctionTemplate> point_templ = FunctionTemplate::New(isolate);
//assign the "SessionBridge" name to the new class template
point_templ->SetClassName(v8::String::NewFromUtf8(isolate,
"SessionBridge"));
//access the class template
Handle<ObjectTemplate> point_proto = point_templ->PrototypeTemplate();
//associates the "method" string to the callback SessionRequest in the
class template
point_proto->Set(v8::String::NewFromUtf8(isolate, "request"),
FunctionTemplate::New(isolate, SessionRequest));
//associates the "method" string to the callback SessionLog in the
class template
point_proto->Set(v8::String::NewFromUtf8(isolate, "log"),
FunctionTemplate::New(isolate, SessionLog));
//access the instance pointer of our new class template
Handle<ObjectTemplate> point_inst = point_templ->InstanceTemplate();
//set the internal fields of the class as we have the SessionBridge
class internally
point_inst->SetInternalFieldCount(1);
//get class template
Handle<Function> point_ctor = point_templ->GetFunction();
//get class instance
Local<Object> js_session = point_ctor->NewInstance();
//build the "bridge" between c++ and javascript by associating the
'session_ptr' pointer to the first internal
//field of the object
js_session->SetInternalField(0, External::New(isolate,session_ptr));
context->Global()->Set(v8::String::NewFromUtf8(isolate, "session"),
js_session);
I want to replace the SessionBridge instance (line 1) disposing the
previous one
SessionBridge* session_ptr = new SessionBridge(session);
Local<Object> global1 = isolate->GetCurrentContext()->Global();
Local<Object> obj1 =
Local<Object>::Cast(global1->Get(v8::String::NewFromUtf8(isolate,
"session")));
SessionBridge* session_ptr = new SessionBridge(session);
obj1->SetInternalField(0, External::New(isolate,session_ptr));
Thanks
Fabio
