◆ GetClientData()

v8::Debug::ClientData * v8::internal::MessageImpl::GetClientData ( ) const

virtual

Client data passed with the corresponding request if any.

This is the client_data data value passed into Debug::SendCommand along with the request that led to the message or NULL if the message is an event. The debugger takes ownership of the data and will delete it even if there is no message handler.

Implements v8::Debug::Message.

◆ GetEventContext()

v8::Handle< v8::Context > v8::internal::MessageImpl::GetEventContext ( ) const

virtual

Get the context active when the debug event happened.

Note this is not the current active context as the JavaScript part of the debugger is running in its own context which is entered at this point.

Implements v8::Debug::Message.

Don't store these cross callbacks as their content becomes invalid. These objects are from the debugger event that started the debug message loop.
