class | Object |
An object reference that is independent of any handle scope. Where a Local handle only lives as long as the HandleScope in which it was allocated, a PersistentBase handle remains valid until it is explicitly disposed.
A persistent handle contains a reference to a storage cell within the v8 engine which holds an object value and which is updated by the garbage collector whenever the object is moved. A new storage cell can be created using the constructor or PersistentBase::Reset and existing handles can be disposed using PersistentBase::Reset.

bool IsNearDeath |
Checks if the handle holds the only reference to an object.

References Internals::GetNodeState(), Internals::kNodeStateIsNearDeathValue, and Internals::kNodeStateIsPendingValue.
bool IsWeak |
Returns true if the handle's reference is weak.

void MarkIndependent |
Marks the reference to this object independent. Garbage collector is free to ignore any object groups containing this object. Weak callback for an independent handle should not assume that it will be preceded by a global GC prologue callback or followed by a global GC epilogue callback.
Definition at line 7281 of file v8.h.
References Internals::kNodeIsIndependentShift, and Internals::UpdateNodeFlag().
void MarkPartiallyDependent |
Marks the reference to this object partially dependent. Partially dependent handles only depend on other partially dependent handles and these dependencies are provided through object groups. It provides a way to build smaller object groups for young objects that represent only a subset of all external dependencies. This mark is automatically cleared after each garbage collection.

Install a finalization callback on this object. NOTE: There is no guarantee as to when or even if the callback is invoked. The invocation is performed solely on a best effort basis. As always, GC-based finalization should not be relied upon for any critical form of resource management!
uint16_t WrapperClassId |
Returns the class ID previously assigned to this handle or 0 if no class ID was previously assigned.
