Method Detail

toCompletableFuture

public static <T> List<CompletableFuture<T>> toCompletableFuture(List<? extends org.apache.jackrabbit.guava.common.util.concurrent.ListenableFuture<T>> listenableFutures)

toCompletableFuture

public static <T> CompletableFuture<T> toCompletableFuture(org.apache.jackrabbit.guava.common.util.concurrent.ListenableFuture<T> listenableFuture)

Converts a ListenableFuture to a CompletableFuture.

The returned CompletableFuture will be completed when the ListenableFuture completes, either with its result or with an exception if the ListenableFuture fails.

Type Parameters:

T - the result type

Parameters:

listenableFuture - the ListenableFuture to convert

Returns:

a CompletableFuture representing the same computation

toListenableFuture

public static <T> org.apache.jackrabbit.guava.common.util.concurrent.ListenableFuture<T> toListenableFuture(CompletableFuture<T> completableFuture)

Converts a Java CompletableFuture to a Guava ListenableFuture.

The returned ListenableFuture will complete when the given CompletableFuture completes, with the same result or exception. This is a one-way conversion; cancelling the ListenableFuture will not cancel the original CompletableFuture.

Type Parameters:

T - the type of the future result

Parameters:

completableFuture - the Java CompletableFuture to convert

Returns:

a Guava ListenableFuture that completes when the CompletableFuture completes
