Detailed Description

template<class T>
class v8::Global< T >

A PersistentBase which has move semantics.

Note: Persistent class hierarchy is subject to future changes.

Member Typedef Documentation

◆ MoveOnlyTypeForCPP03

template<class T >
using v8::Global< T >::MoveOnlyTypeForCPP03 = void

Definition at line 399 of file v8-persistent-handle.h.

Constructor & Destructor Documentation

◆ Global() [1/5]

template<class T >
V8_INLINE v8::Global< T >::Global ( )
default

A Global with no storage cell.

◆ Global() [2/5]

template<class T >
template<class S >
requires (std::is_base_of_v<T, S>)
V8_INLINE v8::Global< T >::Global ( Isolate * isolate,
Local< S > that )
inline

Construct a Global from a Local with automatic up casting. 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 363 of file v8-persistent-handle.h.

◆ Global() [3/5]

template<class T >
template<class S >
requires (std::is_base_of_v<T, S>)
V8_INLINE v8::Global< T >::Global ( Isolate * isolate,
const PersistentBase< S > & that )
inline

Construct a Global from a PersistentBase with automatic up casting. 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 374 of file v8-persistent-handle.h.

◆ Global() [4/5]

template<class T >
v8::Global< T >::Global ( Global< T > && other)

Move constructor.

Definition at line 532 of file v8-persistent-handle.h.

◆ ~Global()

template<class T >
V8_INLINE v8::Global< T >::~Global ( )
inline

Definition at line 383 of file v8-persistent-handle.h.

Here is the call graph for this function:

◆ Global() [5/5]

template<class T >
v8::Global< T >::Global ( const Global< T > & )
delete

Member Function Documentation

◆ operator=() [1/3]

template<class T >
void v8::Global< T >::operator= ( const Global< T > & )
delete

◆ operator=() [2/3]

template<class T >
template<class S >
V8_INLINE Global & v8::Global< T >::operator= ( Global< S > && rhs)

Move via assignment.

◆ operator=() [3/3]

template<class T >
template<class S >
Global< T > & v8::Global< T >::operator= ( Global< S > && rhs)

Definition at line 541 of file v8-persistent-handle.h.

Here is the call graph for this function:

◆ Pass()

template<class T >
Global v8::Global< T >::Pass ( )
inline

Pass allows returning uniques from functions, etc.
