Synced (cactoos 0.55.0 API)

java.lang.Object
- org.cactoos.scalar.Synced<T>

Type Parameters:

T - Type of result

All Implemented Interfaces:

Scalar<T>
```
public final class Synced<T>
extends Object
implements Scalar<T>
```
Scalar that is thread-safe.
This class implements Scalar, which throws a checked Exception. This may not be convenient in many cases. To make it more convenient and get rid of the checked exception you can use the Unchecked decorator. Or you may use IoChecked to wrap it in an IOException.
```
 final List<Integer> list = new LinkedList<>();
 final int threads = 100;
 new RunsInThreads<>(
     new SyncScalar<>(() -> list.add(1)), threads
 ); // list.size() will be equal to threads value
 
```
Objects of this class are thread-safe.
