Package com.azure.core.util

Class IterableStream<T>

java.lang.Object

com.azure.core.util.IterableStream<T>

Type Parameters:

T - The type of value in this Iterable.

All Implemented Interfaces:

Iterable<T>

Direct Known Subclasses:

ContinuablePagedIterable

public class IterableStream<T>
extends Object
implements Iterable<T>

This class provides utility to iterate over values using standard 'for-each' style loops or to convert them into a Stream and operate in that fashion.

Code sample using Stream

 // process the stream
 myIterableStream.stream().forEach(resp -> {
     if (resp.getStatusCode() == HttpURLConnection.HTTP_OK) {
         System.out.printf("Response headers are %s. Url %s%n", resp.getDeserializedHeaders(),
             resp.getRequest().getUrl());
         resp.getElements().forEach(value -> System.out.printf("Response value is %d%n", value));
     }
 });
 

Code sample using Iterator

 // Iterate over iterator
 for (PagedResponseBase<String, Integer> resp : myIterableStream) {
     if (resp.getStatusCode() == HttpURLConnection.HTTP_OK) {
         System.out.printf("Response headers are %s. Url %s%n", resp.getDeserializedHeaders(),
             resp.getRequest().getUrl());
         resp.getElements().forEach(value -> System.out.printf("Response value is %d%n", value));
     }
 }
 

Code sample using Stream and filter

 // process the stream
 myIterableStream.stream().filter(resp -> resp.getStatusCode() == HttpURLConnection.HTTP_OK)
     .limit(10)
     .forEach(resp -> {
         System.out.printf("Response headers are %s. Url %s%n", resp.getDeserializedHeaders(),
             resp.getRequest().getUrl());
         resp.getElements().forEach(value -> System.out.printf("Response value is %d%n", value));
     });

Constructor Detail

IterableStream

public IterableStream(Flux<T> flux)

Creates an instance with the given Flux.

Parameters:

flux - Flux of items to iterate over.

Throws:

NullPointerException - If flux is null.

IterableStream

public IterableStream(Iterable<T> iterable)

Creates an instance with the given Iterable.

Parameters:

iterable - Collection of items to iterate over.

Throws:

NullPointerException - If iterable is null.

Method Detail

stream

public Stream<T> stream()

Utility function to provide Stream of value T.

Returns:

Stream of value T.

iterator

public Iterator<T> iterator()

Utility function to provide Iterator of value T.

Specified by:

iterator in interface Iterable<T>

Returns:

Iterator of value T.

of

public static <T> IterableStream<T> of(Iterable<T> iterable)

Creates an IterableStream from an Iterable.

An empty IterableStream will be returned if the input iterable is null.

Type Parameters:

Parameters:

iterable - Collection of items to iterate over.

Returns:

An IterableStream based on the passed collection.
