Detailed Description

template<typename T>
class v8::TracedReference< T >

A traced handle without destructor that clears the handle. The embedder needs to ensure that the handle is not accessed once the V8 object has been reclaimed. This can happen when the handle is not passed through the EmbedderHeapTracer. For more details see TracedReferenceBase.

The reference assumes the embedder has precise knowledge about references at all times. In case V8 needs to separately handle on-stack references, the embedder is required to set the stack start through |EmbedderHeapTracer::SetStackStart|.

Constructor & Destructor Documentation

◆ TracedReference() [1/6]

TracedReference ( )
inline

An empty TracedReference without storage cell.

Definition at line 1089 of file v8.h.

References V8::TracedReferenceBase.

◆ TracedReference() [2/6]

TracedReference ( Isolate isolate,
Local< S >  that 
)
inline

Construct a TracedReference from a Local.

When the Local is non-empty, a new storage cell is created pointing to the same object.

References V8::TracedReferenceBase.

◆ TracedReference() [3/6]

V8_INLINE TracedReference ( TracedReference< T > &&  other)
inline

Move constructor initializing TracedReference from an existing one.

Definition at line 1108 of file v8.h.

◆ TracedReference() [4/6]

V8_INLINE TracedReference ( TracedReference< S > &&  other)
inline

Move constructor initializing TracedReference from an existing one.

Definition at line 1118 of file v8.h.

◆ TracedReference() [5/6]

V8_INLINE TracedReference ( const TracedReference< T > &  other)
inline

Copy constructor initializing TracedReference from an existing one.

Definition at line 1127 of file v8.h.

◆ TracedReference() [6/6]

V8_INLINE TracedReference ( const TracedReference< S > &  other)
inline

Copy constructor initializing TracedReference from an existing one.

Member Function Documentation

◆ As()

V8_INLINE TracedReference<S>& As ( ) const
inline

Definition at line 1172 of file v8.h.

References V8::TracedReference.

◆ 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.

Definition at line 1181 of file v8.h.

◆ operator=() [1/6]

TracedReference< T > & operator= ( const TracedReference< T > &  rhs)

Copy assignment operator initializing TracedGlobal from an existing one.

Definition at line 11054 of file v8.h.

◆ operator=() [2/6]

V8_INLINE TracedReference& operator= ( const TracedReference< S > &  rhs)

Copy assignment operator initializing TracedGlobal from an existing one.

◆ operator=() [3/6]

TracedReference<T>& operator= ( const TracedReference< S > &  rhs)

Definition at line 11036 of file v8.h.

◆ operator=() [4/6]

TracedReference< T > & operator= ( TracedReference< T > &&  rhs)

Move assignment operator initializing TracedGlobal from an existing one.

Definition at line 11044 of file v8.h.

◆ operator=() [5/6]

V8_INLINE TracedReference& operator= ( TracedReference< S > &&  rhs)

Move assignment operator initializing TracedGlobal from an existing one.

◆ operator=() [6/6]

TracedReference<T>& operator= ( TracedReference< S > &&  rhs)

Definition at line 11028 of file v8.h.

◆ Reset() [1/2]

V8_INLINE void Reset ( Isolate isolate,
const Local< S > &  other 
)

If non-empty, destroy the underlying storage cell and create a new one with the contents of other if other is non empty

◆ Reset() [2/2]

void Reset ( Isolate isolate,
const Local< S > &  other 
)

Definition at line 11017 of file v8.h.
