Method Detail

ofExpectedSize

public static <T> Async.CombinedBuilder<T> ofExpectedSize(int expectedSize)

Combines 0 or more CF into one. It is a wrapper around CompletableFuture.allOf.

Type Parameters:

T - for two

Parameters:

expectedSize - how many we expect

Returns:

a combined builder of CFs

each

public static <T,U> java.util.concurrent.CompletableFuture<java.util.List<U>> each(java.util.Collection<T> list,
                                                                                   java.util.function.BiFunction<T,java.lang.Integer,java.util.concurrent.CompletableFuture<U>> cfFactory)

eachSequentially

public static <T,U> java.util.concurrent.CompletableFuture<java.util.List<U>> eachSequentially(java.lang.Iterable<T> list,
                                                                                               Async.CFFactory<T,U> cfFactory)

toCompletableFuture

public static <T> java.util.concurrent.CompletableFuture<T> toCompletableFuture(T t)

Turns an object T into a CompletableFuture if it's not already

Type Parameters:

T - for two

Parameters:

t - - the object to check

Returns:

a CompletableFuture

tryCatch

public static <T> java.util.concurrent.CompletableFuture<T> tryCatch(java.util.function.Supplier<java.util.concurrent.CompletableFuture<T>> supplier)

exceptionallyCompletedFuture

public static <T> java.util.concurrent.CompletableFuture<T> exceptionallyCompletedFuture(java.lang.Throwable exception)
