Implementing JavaScript Classes in C++

Class Structure

For publicly accessible Constructor and Prototype, create 3 classes:

1. class Foo : public JSC::DestructibleObject - if C++ fields exist; otherwise use JSC::constructEmptyObject with putDirectOffset
2. class FooPrototype : public JSC::JSNonFinalObject
3. class FooConstructor : public JSC::InternalFunction

No public constructor? Only Prototype and class needed.

Iso Subspaces

Classes with C++ fields need subspaces in:

• src/jsc/bindings/webcore/DOMClientIsoSubspaces.h
• src/jsc/bindings/webcore/DOMIsoSubspaces.h
