Member Function Documentation

ResetRoot()

virtual void v8::EmbedderRootsHandler::ResetRoot ( const v8::TracedReference< v8::Value > &  handle )

pure virtual

Used in combination with |IsRoot|. Called by V8 when an object that is backed by a handle is reclaimed by a non-tracing garbage collection. It is up to the embedder to reset the original handle.

Note that the |handle| is different from the handle that the embedder holds for retaining the object. It is up to the embedder to find the original handle via the object or class id.

TryResetRoot()

virtual bool v8::EmbedderRootsHandler::TryResetRoot ( const v8::TracedReference< v8::Value > &  handle )

inlinevirtual

Similar to |ResetRoot()|, but opportunistic. The function is called in parallel for different handles and as such must be thread-safe. In case, |false| is returned, |ResetRoot()| will be recalled for the same handle.
