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.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`void`	`add(long x)`	Add the given value.
`default void`	`decrement()`	Equivalent to `add(-1)`.
`default double`	`doubleValue()`	Returns the `sum()` as a `double` after a widening primitive conversion.
`default float`	`floatValue()`	Returns the `sum()` as a `float` after a widening primitive conversion.
`default void`	`increment()`	Equivalent to `add(1)`.
`default int`	`intValue()`	Returns the `sum()` as a `int` after a narrowing primitive conversion.
`default long`	`longValue()`	Equivalent to `sum()`.
`void`	`reset()`	Resets the variables maintaining the sum to zero.
`long`	`sum()`	Returns the current sum.
`long`	`sumThenReset()`	Equivalent in effect to `sum()` followed by `reset()`.
