Hi Zhou.
I have a question about the objects referencing between
Javasciptcore
and WebCore:
JSNode uses m_impl to reference a Node in WebCore. And when
KJS::Collector::collect() is called the function mark() of each
JSNode is
invoked to keep the corresponding Node in WebCore alive in memory.
That's not quite accurate.
m_impl is reference-counted -- nothing specific needs to happen during
garbage collection in order to keep m_impl alive.
The purpose of marking JSNode objects is to keep alive the JavaScript
wrapper around m_impl, to preserve custom properties set through the
DOM API.
