FreezableAtomicReference

class FreezableAtomicReference<T>(value_: T)(source)

Note: this class is useful only with legacy memory manager. Please use AtomicReference instead.

An atomic reference to a Kotlin object. Can be used in concurrent scenarious, but must be frozen first, otherwise behaves as regular box for the value. If frozen, shall be zeroed out once no longer needed. Otherwise memory leak could happen. To detect such leaks kotlin.native.internal.GC.detectCycles in debug mode could be helpful.
