Method Details

mapAsync

public static <K,
V> CompletableFuture<Map<K,V>> mapAsync(Collection<K> keys,
 Function<K,CompletableFuture<V>> valueMapper)

Maps keys to values by applying a mapping function asynchronously.

Type Parameters:

V - Type of value

Parameters:

keys - A collection of keys.

valueMapper - A function that returns a CompletableFuture<V> for every key.

Returns:

A future that completes with a map of keys to the completed result of applying the mapping function. If the mapping function completes exceptionally, the resulting future will also complete exceptionally. @ param Type of keys

mapAsync

public static <C,
K,
V> CompletableFuture<Map<K,V>> mapAsync(Collection<C> coll,
 Function<C,K> keyMapper,
 Function<C,CompletableFuture<V>> valueMapper)

Maps keys to values by applying a mapping function asynchronously.

Type Parameters:

V - Type of value

Parameters:

coll - A collection where elements will be mapped to keys and value by the provided functions.

valueMapper - A function that returns a CompletableFuture<V> for every key.

Returns:

A future that completes with a map of keys to the completed result of applying the mapping function. If the mapping function completes exceptionally, the resulting future will also complete exceptionally. @ param Type of keys
