dagger.producers.internal.MapProducer<K,V>

All Implemented Interfaces:

Producer<Map<K,V>>

@Beta
public final class MapProducer<K,V>
extends AbstractProducer<Map<K,V>>

A Producer implementation used to implement Map bindings. This producer returns a Map<K, V> which is populated by calls to the delegate Producer.get() methods.

Method Summary

Modifier and Type	Method and Description
com.google.common.util.concurrent.ListenableFuture<Map<K,V>>	compute(ProducerMonitor unusedMonitor) Computes this producer's future, which is then cached in AbstractProducer.get().
static <K,V> MapProducer<K,V>	create(Producer<Map<K,Producer<V>>> mapProducerProducer) Returns a producer of Map<K, V>, where the map is derived from the given map of producers by waiting for those producers' resulting futures.

Method Detail

create

public static <K,V> MapProducer<K,V> create(Producer<Map<K,Producer<V>>> mapProducerProducer)

Returns a producer of Map<K, V>, where the map is derived from the given map of producers by waiting for those producers' resulting futures. The iteration order mirrors the order of the input map.

If any of the delegate producers, or their resulting values, are null, then this producer's future will fail with a NullPointerException.

Canceling this future will attempt to cancel all of the component futures, and if any of the component futures fails or is canceled, this one is, too.

compute

public com.google.common.util.concurrent.ListenableFuture<Map<K,V>> compute(ProducerMonitor unusedMonitor)

Description copied from class: AbstractProducer

Computes this producer's future, which is then cached in AbstractProducer.get().
