Detailed Description

template<class T, class M>
class v8::Persistent< T, M >

A PersistentBase which allows copy and assignment.

Copy, assignment and destructor behavior is controlled by the traits class M.

Note: Persistent class hierarchy is subject to future changes.

Constructor & Destructor Documentation

Persistent() [1/5]

template<class T , class M >

V8_INLINE v8::Persistent< T, M >::Persistent ( )

inline

A Persistent with no storage cell.

Definition at line 662 of file v8.h.

Persistent() [2/5]

template<class T , class M >

template<class S >

V8_INLINE v8::Persistent< T, M >::Persistent ( Isolate *  isolate, Local< S >  that  )

inline

Construct a Persistent from a Local. When the Local is non-empty, a new storage cell is created pointing to the same object, and no flags are set.

Definition at line 669 of file v8.h.

Persistent() [3/5]

template<class T , class M >

template<class S , class M2 >

V8_INLINE v8::Persistent< T, M >::Persistent ( Isolate *  isolate, const Persistent< S, M2 > &  that  )

inline

Construct a Persistent from a Persistent. When the Persistent is non-empty, a new storage cell is created pointing to the same object, and no flags are set.

Definition at line 679 of file v8.h.

Persistent() [4/5]

template<class T , class M >

V8_INLINE v8::Persistent< T, M >::Persistent ( const Persistent< T, M > &  that )

inline

The copy constructors and assignment operator create a Persistent exactly as the Persistent constructor, but the Copy function from the traits class is called, allowing the setting of flags based on the copied Persistent.

Definition at line 689 of file v8.h.

Persistent() [5/5]

template<class T , class M >

template<class S , class M2 >

V8_INLINE v8::Persistent< T, M >::Persistent ( const Persistent< S, M2 > &  that )

inline

Definition at line 693 of file v8.h.

~Persistent()

template<class T , class M >

V8_INLINE v8::Persistent< T, M >::~Persistent ( )

inline

The destructor will dispose the Persistent based on the kResetInDestructor flags in the traits class. Since not calling dispose can result in a memory leak, it is recommended to always set this flag.

Persistent is a way to create a strong pointer from an off-heap object to another on-heap object. As long as the Persistent handle is alive the GC will keep the object pointed to alive. The Persistent handle is always a GC root from the point of view of the GC. Persistent must be constructed and destructed in the same thread.
