Class Pointer.DeallocatorReference

java.lang.Object

java.lang.ref.Reference<Pointer>

java.lang.ref.PhantomReference<Pointer>

org.bytedeco.javacpp.Pointer.DeallocatorReference

All Implemented Interfaces:

Pointer.Deallocator, Pointer.ReferenceCounter

Direct Known Subclasses:

Pointer.CustomDeallocator, Pointer.NativeDeallocator, Pointer.ProxyDeallocator

Enclosing class:

Pointer

static class Pointer.DeallocatorReference
extends PhantomReference<Pointer>
implements Pointer.Deallocator, Pointer.ReferenceCounter

A subclass of PhantomReference that also acts as a linked list to keep their references alive until they get garbage collected. Also keeps track of total allocated memory in bytes, to have it call System.gc() when that amount reaches Pointer.maxBytes, and implements reference counting with an AtomicInteger count.
