Interface LongStream

All Superinterfaces:
AutoCloseable, BaseStream<Long,LongStream>

public interface LongStream extends BaseStream<Long,LongStream>
A sequence of primitive long-valued elements supporting sequential and parallel aggregate operations. This is the long primitive specialization of Stream.

The following example illustrates an aggregate operation using Stream and LongStream, computing the sum of the weights of the red widgets:


     long sum = widgets.stream()
                       .filter(w -> w.getColor() == RED)
                       .mapToLong(w -> w.getWeight())
                       .sum();
 
See the class documentation for Stream and the package documentation for java.util.stream for additional specification of streams, stream operations, stream pipelines, and parallelism.
