Enclosing interface:

ContextAwareScheduler

public static final class ContextAwareScheduler.ContextCaptureStrategy
extends Object

Define how a scheduler captures a Vert.x Context.

Method Summary

Modifier and Type	Method	Description
ScheduledExecutorService	withContext(Context context)	Actions will be run on an explicit Context.
ScheduledExecutorService	withCurrentContext()	Actions will be run on a context that is captured from the thread that is calling this method.
ScheduledExecutorService	withGetOrCreateContext(Vertx vertx)	Actions will be run on a context that is captured by calling Vertx.getOrCreateContext() when a scheduling method is being called like ScheduledExecutorService.schedule(Runnable, long, TimeUnit).
ScheduledExecutorService	withGetOrCreateContextOnCurrentThread(Vertx vertx)	Actions will be run on a context that is captured by calling Vertx.getOrCreateContext() on the thread that is calling this method.

Method Detail

withContext

public ScheduledExecutorService withContext(Context context)

Actions will be run on an explicit Context.

Parameters:

context - the context, cannot be null

Returns:

the scheduler

withGetOrCreateContext

public ScheduledExecutorService withGetOrCreateContext(Vertx vertx)

Actions will be run on a context that is captured by calling Vertx.getOrCreateContext() when a scheduling method is being called like ScheduledExecutorService.schedule(Runnable, long, TimeUnit).

Important. Note that in many cases such as UniDelayOnItem the scheduling operation happens on a worker thread and not a Vert.x thread, so withGetOrCreateContextOnCurrentThread(Vertx) might be the better option when data is being shared through the context.

Parameters:

vertx - the Vert.x object, cannot be null

Returns:

the scheduler

withGetOrCreateContextOnCurrentThread

public ScheduledExecutorService withGetOrCreateContextOnCurrentThread(Vertx vertx)

Actions will be run on a context that is captured by calling Vertx.getOrCreateContext() on the thread that is calling this method. This is different to withGetOrCreateContext(Vertx) which is late bound.

Parameters:

vertx - the Vert.x object, cannot be null

Returns:

the scheduler

withCurrentContext

public ScheduledExecutorService withCurrentContext()
                                            throws IllegalStateException

Actions will be run on a context that is captured from the thread that is calling this method. An exception is raised when the current thread is not a Vert.x thread and hence has no associated Context.

Returns:

the scheduler

Throws:

IllegalStateException - when the current thread is not a Vert.x thread
