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:

PagedIterable

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. All the values are preserved even if they are traversed multiple times.

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.getItems().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.getItems().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.getItems().forEach(value -> {
            System.out.printf("Response value is %d%n", value);
        });
    });
