Get()

v8::Local< v8::Value > Get

(

v8::Isolate *

isolate

)

const

Construct a Local<Value> from this handle.

GetSlotThreadSafe()

const void* GetSlotThreadSafe ( ) const

inlineprotected

Get this reference in a thread-safe way

Referenced by TracedReferenceBase::IsEmptyThreadSafe().

IsEmpty()

bool IsEmpty ( ) const

inline

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

IsEmptyThreadSafe()

bool IsEmptyThreadSafe ( ) const

inline

Returns true if this TracedReference is empty, i.e., has not been assigned an object. This version of IsEmpty is thread-safe.

uint16_t

class_id

)

Assigns a wrapper class ID to the handle.
