Class AndInThreads

java.lang.Object

org.cactoos.scalar.AndInThreads

All Implemented Interfaces:

Scalar<Boolean>

public final class AndInThreads
extends Object
implements Scalar<Boolean>

Logical conjunction, in multiple threads.

This class can be effectively used to iterate through a collection, just like Stream.forEach(java.util.function.Consumer) works:

 new AndInThreads(
   new IterableOf("Mary", "John", "William", "Napkin"),
   name -> System.out.printf("The name: %s\n", name)
 ).value();

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 UncheckedScalar or IoCheckedScalar decorators.

There is no thread-safety guarantee.
