i'm looking for a method/solution for sharing js objects declared into a context (i.e. context A) into another context (i.e. Context B). Both are in the same isolate.
In detail:
I'm using v8 c++ wrapper for make available c++ class (i.e. cppClass) into js code. So, i can call cppClass.myfunction() or cppClass.myProperty directly into js code.

I have an only one isolate, and a main context for loading and running a complex js file (composed by many js files and many objects/functions declared).

Furthermore i have others contexts where other simple js code is running. All contexts are in the same isolate.

Suppose to have an AObject declared and used in the contextA, which has a property like AObject.foo=10 . I'm wondering if is it possible to access to AObject in the ContextB and read/change AObject.foo property such as :

 // JS code in ContextA
 var AObject=new cppClass();
 AOBject.foo=10;
 ...

// JS code in ContextB
 var newvalue=AObject.foo +1; //or something like myWrapMethod.AObject.foo+1;
 Console.Log(" The new value is : " + newvalue );
 // The new value is : 11

Can i access to AObject (i.e. call its functions or set its attributes/properties) from ContextB?
Thank you in advance

a possible answer to my question could be the following approach. In c++, suppose to have the following code:

 Handle<Context> contextA=myIsolate::GetCurrentContext();
 ... some code
 Handle<Context> contextB=GetMyBContext();
 ... some code

 contextA->Enter(); // change the context to A Context

 auto global_obj = contextA->Global();
 v8::Local<v8::Value> desiredValue = global_obj->Get(String::NewFromUtf8(myIsolate,"AObject"));
 contextA->Exit(); // change the context to B Context
 // Now AObject can be used also in the context B (another script js)
 myIsolate->GetCurrentContext()->Global()->Set(v8::String::NewFromUtf8(myIsolate, "AObject"), desiredValue ->ToObject());

After that, in the js file (related to B context), i can use AObject with the same values it has in AContext.

Hope to be useful.
Kind regards.

You should set both Context security tokens to be the same.
Then you can get an object Ref from a Context, and store/use it from the other.

From v8.h header file:

 /**
 * Sets the security token for the context. To access an object in
 * another context, the security tokens must match.
 */
 void SetSecurityToken(Local<Value> token);
