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.

using UntracedMember = internal::BasicMember<T, internal::UntracedMemberTag, internal::NoWriteBarrierPolicy> |
UntracedMember is a pointer to an on-heap object that is not traced for some reason. Do not use this unless you know what you are doing. Keeping raw pointers to on-heap objects is prohibited unless used from stack. Pointee must be kept alive through other means.
using WeakCallback = void (*)(const LivenessBroker&, const void*) |
using WeakMember = internal::BasicMember<T, internal::WeakMemberTag, internal::DijkstraWriteBarrierPolicy> |
WeakMember is similar to Member in that it is used to point to other garbage collected objects. However instead of creating a strong pointer to the object, the WeakMember creates a weak pointer, which does not keep the pointee alive. Hence if all pointers to to a heap allocated object are weak the object will be garbage collected. At the time of GC the weak pointers will automatically be set to null.
WeakPersistent is a way to create a weak pointer from an off-heap object to an on-heap object. The pointer is automatically cleared when the pointee gets collected. WeakPersistent must be constructed and destructed in the same thread.

V8_EXPORT void cppgc::InitializeProcess | ( | PageAllocator * | page_allocator | ) |
Process-global initialization of the garbage collector. Must be called before creating a Heap.
Can be called multiple times when paired with ShutdownProcess()
.
page_allocator | The allocator used for maintaining meta data. Must not change between multiple calls to InitializeProcess. |
V8_INLINE T* cppgc::MakeGarbageCollected | ( | AllocationHandle & | handle, |
AdditionalBytes | additional_bytes, | ||
Args &&... | args | ||
) |
Constructs a managed object of type T where T transitively inherits from GarbageCollected. Created objects will have additional bytes appended to it. Allocated memory would suffice for sizeof(T) + additional_bytes
.
additional_bytes | Denotes how many bytes to append to T. |
args | List of arguments with which an instance of T will be constructed. |

Definition at line 278 of file allocation.h.
V8_EXPORT void cppgc::ShutdownProcess | ( | ) |
Must be called after destroying the last used heap. Some process-global metadata may not be returned and reused upon a subsequent InitializeProcess()
call.
