Method Detail

createFutureProduced

public static <T> com.google.common.util.concurrent.ListenableFuture<Produced<T>> createFutureProduced(com.google.common.util.concurrent.ListenableFuture<T> future)

Returns a future of Produced that represents the completion (either success or failure) of the given future. If the input future succeeds, then the resulting future also succeeds with a successful Produced; if the input future fails, then the resulting future succeeds with a failing Produced.

Cancelling the resulting future will propagate the cancellation to the input future; but cancelling the input future will trigger the resulting future to succeed with a failing Produced.

createFutureSingletonSet

public static <T> com.google.common.util.concurrent.ListenableFuture<Set<T>> createFutureSingletonSet(com.google.common.util.concurrent.ListenableFuture<T> future)

Returns a future of a Set that contains a single element: the result of the input future.

producerFromProvider

public static <T> Producer<T> producerFromProvider(javax.inject.Provider<T> provider)

Returns a producer that immediately executes the binding logic for the given provider every time it is called.

immediateProducer

public static <T> Producer<T> immediateProducer(T value)

Returns a producer that succeeds with the given value.

immediateFailedProducer

public static <T> Producer<T> immediateFailedProducer(Throwable throwable)

Returns a producer that fails with the given exception.
