Interface LongAdder

All Known Implementing Classes:
AtomicLongLongAdder, JreLongAdder
public interface LongAdder
Interface mirroring the LongAdder API, with implementation that varies based on availability of LongAdder. This offers compatibility for Android 21 without compromising performance in runtimes where LongAdder is available.

This class is internal and is hence not for public use. Its APIs are unstable and can change at any time.
