Referenced by BasicTracedReference< T >::operator*(), and BasicTracedReference< T >::operator->().

Get()

V8_INLINE v8::Local< v8::Value > Get ( v8::Isolate *  isolate ) const

inline

Construct a Local<Value> from this handle.

GetSlotThreadSafe()

const void * GetSlotThreadSafe ( ) const

inlineprotected

Get this reference in a thread-safe way

IsEmpty()

bool IsEmpty ( ) const

inline

Returns true if the reference is empty, i.e., has not been assigned object.
