Method Detail

executor

public static Executor executor(io.vertx.core.Vertx vertx)

Create an executor for a Vertx object, actions are executed on the event loop.

Parameters:

vertx - the vert.x object

Returns:

the executor

executor

public static Executor executor(io.vertx.core.Context context)

Create an executor for a Context, actions are executed on the event loop of this context.

Parameters:

context - the context object

Returns:

the executor

blockingExecutor

public static Executor blockingExecutor(io.vertx.core.Vertx vertx)

Create an executor for a Vertx object, actions can be blocking, they are not executed on Vert.x event loop.

Parameters:

vertx - the ver.tx object

Returns:

the executor

blockingExecutor

public static Executor blockingExecutor(io.vertx.core.Vertx vertx,
                                        boolean ordered)

Create an executor for a Vertx object, actions can be blocking, they are not executed on Ver.tx event loop.

Parameters:

vertx - the vert.x object

ordered - if true then if when tasks are scheduled several times on the same context, the executions for that context will be executed serially, not in parallel. if false then they will be no ordering guarantees

Returns:

the executor

blockingExecutor

public static Executor blockingExecutor(io.vertx.core.WorkerExecutor worker)

Create a scheduler for a WorkerExecutor object, actions are executed on the threads of this executor.

Parameters:

worker - the worker executor object

Returns:

the executor

unwrap

public static Class unwrap(Class<?> type)

Unwrap the type used in Mutiny.

Parameters:

type - the type to unwrap

Returns:

the unwrapped type

toSubscriber

public static <T> WriteStreamSubscriber<T> toSubscriber(io.vertx.core.streams.WriteStream<T> stream)

Adapts a Vert.x WriteStream to a Mutiny Subscriber.

After subscription, the original WriteStream handlers should not be used anymore as they will be used by the adapter.

Parameters:

stream - the stream to adapt

Returns:

the adapted Subscriber

toSubscriber

public static <R,T> WriteStreamSubscriber<R> toSubscriber(io.vertx.core.streams.WriteStream<T> stream,
                                                          Function<R,T> mapping)

Like toSubscriber(WriteStream), except the provided mapping function is applied to each item.
