hi guys. i'm trying to make an IRCClient class. it has a method called
"connect". Here's my code
v8::Handle<v8::Value> IRCClient(const v8::Arguments& args) {
v8::HandleScope handle_scope;
v8::Local<v8::Object> self = args.Holder();
printf("IRCClient called, internal field count=%d\n", self-
>InternalFieldCount());
IRC::Client *c = new IRC::Client;
self->SetInternalField(0, v8::External::New(c));
return v8::Undefined();
}
v8::Handle<v8::Value> IRCClientConnect(const v8::Arguments& args) {
printf("IRCClientConnect called\n");
v8::HandleScope handle_scope;
v8::Local<v8::Object> self = args.Holder();
v8::Local<v8::External> wrap = v8::Local<v8::External>::Cast(self-
>GetInternalField(0));
IRC::Client *c = (IRC::Client *)wrap->Value();
v8::String::Utf8Value host(args[0]);
printf("host: %s\n", ToCString(host));
return v8::Undefined();
}
int initjs(int argc, char* argv[]) {
v8::V8::SetFlagsFromCommandLine(&argc, argv, true);
v8::HandleScope handle_scope;
// Create a template for the global object.
v8::Handle<v8::ObjectTemplate> global = v8::ObjectTemplate::New();
// Bind the global 'print' function to the C++ Print callback.
global->Set(v8::String::New("print"),
v8::FunctionTemplate::New(Print));
// Bind the 'quit' function
global->Set(v8::String::New("quit"),
v8::FunctionTemplate::New(Quit));
// Bind the 'version' function
global->Set(v8::String::New("version"),
v8::FunctionTemplate::New(Version));
v8::Local<v8::FunctionTemplate> irct =
v8::FunctionTemplate::New(IRCClient);
v8::Local<v8::ObjectTemplate> ircpt = irct->PrototypeTemplate();
ircpt->SetInternalFieldCount(1);
ircpt->Set("connect", v8::FunctionTemplate::New(IRCClientConnect));
global->Set(v8::String::New("IRCClient"), irct);
// Create a new execution environment containing the built-in
// functions
context = v8::Context::New(NULL, global);
// Enter the newly created execution environment.
return 0;
}
// I'm also using some functions from the sample code
and here's the error i get:
irc = new IRCClient; // this is the code i run
IRCClient called, internal field count=0
#
# Fatal error in v8::Object::SetInternalField()
# Writing internal field out of bounds
#
Aborted
