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]

V8_INLINE Persistent ( )

inline

A Persistent with no storage cell.

Definition at line 651 of file v8.h.

References Local< T >::PersistentBase.

Persistent() [2/5]

V8_INLINE 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 658 of file v8.h.

References Local< T >::PersistentBase.

Persistent() [3/5]

V8_INLINE 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 668 of file v8.h.

References Local< T >::PersistentBase.

Persistent() [4/5]

V8_INLINE 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 678 of file v8.h.

References Local< T >::PersistentBase.

Persistent() [5/5]

V8_INLINE Persistent ( const Persistent< S, M2 > &  that )

inline

Definition at line 682 of file v8.h.

References Local< T >::PersistentBase.

~Persistent()

V8_INLINE ~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.
