Method Details

asMap

Map<RedisClusterNode,CompletableFuture<T>> asMap()

Returns:

map between RedisClusterNode and the CompletionStage

nodes

Collection<RedisClusterNode> nodes()

Returns:

collection of nodes on which the command was executed.

get

CompletionStage<T> get(RedisClusterNode redisClusterNode)

Parameters:

redisClusterNode - the node

Returns:

the completion stage for this node

futures

CompletableFuture<T>[] futures()

Returns:

array of futures.

thenCollect

<R,
A> CompletionStage<R> thenCollect(Collector<? super T,A,R> collector)

Returns a new CompletionStage that, when this stage completes normally, is executed with this stage's results as the argument to the Collector. See the CompletionStage documentation for rules covering exceptional completion.

Parameters:

collector - the Collector to collect this stages results.

Returns:

the new CompletionStage.

stream

default Stream<CompletableFuture<T>> stream()

Returns:

a sequential Stream over the CompletionStages in this collection
