Method Detail

toCompletableFuture

public static <T> CompletableFuture<T> toCompletableFuture(com.google.common.util.concurrent.ListenableFuture<T> listenableFuture,
                                                           Executor executor)

Adapts a ListenableFuture to a CompletableFuture. The provided executor is used to execute the callback as per Futures.addCallback(ListenableFuture, FutureCallback, Executor) On such callback, completion will be performed.

Type Parameters:

T - the type of the listenable future.

Parameters:

listenableFuture - the listenable future to adapt.

executor - the executor where the callback execution is submitted.

Returns:

the completable future.

public static BigInteger getDpnIdFromLowerLayerIfList(List<String> lowerLayerIfList)

Extracts the data plane node Id from a lower layer interface list.

Parameters:

lowerLayerIfList - to extract the data plane node Id from.

Returns:

the data plane node Id.

Throws:

SfcGeniusRuntimeException - wrapping an IllegalArgumentException if the input list does not contain one item only, or if the format of the item is invalid.
