Trying to upgrade to v0.11.10 and higher. The HasInstance from v8 looks
like it is one of the few unchanged pieces in v8 yet no longer compiles as
available. Take code
class Base : public node::ObjectWrap {
public:
...
Handle<Value> Base::applyTransform(const v8::FunctionCallbackInfo<Value>&
args)
{
HandleScope scope(args.GetIsolate());
Base* pThis = ObjectWrap::Unwrap<Base>(args.This());
if (args.Length()!=1 &&
!Transformation::constructor->HasInstance(args[0])) {
ThrowException(Exception::Error(String::New("invalid
transformation")));
return scope.Close(Undefined());
}
....
where the Transformation::constructor is static
Persistent<FunctionTemplate> constructor;
HasInstance is in v8.h#FunctionTemplate and implemented in api.cc.
Not understanding why but get compiler error:
../src/Base.cc: In static member function ‘static
v8::Handlev8::ValueBase::transformed(const v8::FunctionCallbackInfo
v8::Value&)’:
../src/Base.cc:159:57: error: base operand of ‘->’ has non-pointer type
‘v8::Persistent >’
if (args.Length()!=1 && !Transformation::constructor->HasInstance(args[0]))
{
