DoubleAdder

All Known Implementing Classes:

AtomicLongDoubleAdder, JreDoubleAdder
```
public interface DoubleAdder
```
Interface mirroring the DoubleAdder API, with implementation that varies based on availability of DoubleAdder. This offers compatibility for Android 21 without compromising performance in runtimes where DoubleAdder is available.
This class is internal and is hence not for public use. Its APIs are unstable and can change at any time.

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