Dear experts,
Consider the following (javaScript) scripts:
"function fnc(val) { var a = []; a[0] = 1; a[1] = 2; array = a; \n\
b = array; b[0] = 3; array = b; }";
"function fnc(val) { array[0] = 1; array[1] = 2; }";
I'd like to call the function 'fnc' from within the v8-engine C++ code and
intercept all accesses to 'array', whether indexed or not. The code below
fails, cause the last 2 statements override each other, but may give you a
clue where I'm heading.
v8::Handle<v8::ObjectTemplate> tmpl = v8::ObjectTemplate::New(isolate);
tmpl->SetIndexedPropertyHandler(indexed_getter, indexed_setter);
context->Global()->Set(name, tmpl->NewInstance());
context->Global()->SetAccessor(name, getter, setter);
I know I can do something like:
global_tmpl->SetNamedPropertyHandler(named_getter, named_setter);
v8::Handle<v8::Context> context = v8::Context::New(isolate, NULL,
global_tmpl);
v8::Context::Scope context_scope(context);
v8::Handle<v8::ObjectTemplate> tmpl = v8::ObjectTemplate::New(isolate);
tmpl->SetIndexedPropertyHandler(indexed_getter, indexed_setter);
context->Global()->Set(name, tmpl->NewInstance());
The problem is that with SetNamedPropertyHandler() I get callbacks on
access to every token in the script, which I'd like to avoid. I would like
to do something similar to the first code snippet. Any idea how?
BW, I've posted the question above in StackOverflow; see
here<http://stackoverflow.com/questions/22758724/is-there-a-way-to-intercept-a-plain-access-and-an-indexed-access-at-the-same-tim>
.
Also, I'm new to v8 in general and to this mailing list in particular, so
apologies ahead for improper use (of either v8 or the mailing list...)
Thanks,Efi
