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() [1/4]

template<class T, class M>

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

inline

A Persistent with no storage cell.

Definition at line 664 of file v8.h.

Persistent() [2/4]

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 671 of file v8.h.

Persistent() [3/4]

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 681 of file v8.h.

Persistent() [4/4]

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 691 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.
