Vertx (vertx-core 2.1.3 API)

All Known Subinterfaces:

VertxInternal, VertxSPI

All Known Implementing Classes:

DefaultVertx
```
public interface Vertx
```
The control centre of the Vert.x Core API.
You should normally only use a single instance of this class throughout your application. If you are running in the Vert.x container an instance will be provided to you.
If you are using Vert.x embedded, you can create an instance using one of the static VertxFactory.newVertx methods.
This class acts as a factory for TCP/SSL and HTTP/HTTPS servers and clients, SockJS servers, and provides an instance of the event bus, file system and shared data classes, as well as methods for setting and cancelling timers.
Instances of this class are thread-safe.

Method Summary

Methods
Modifier and Type	Method and Description
`boolean`	`cancelTimer(long id)` Cancel the timer with the specified `id`.
`DatagramSocket`	`createDatagramSocket(InternetProtocolFamily family)` Create a new `DatagramSocket`.
`DnsClient`	`createDnsClient(java.net.InetSocketAddress... dnsServers)` Return the `DnsClient`
`HttpClient`	`createHttpClient()` Create a HTTP/HTTPS client
`HttpServer`	`createHttpServer()` Create an HTTP/HTTPS server
`NetClient`	`createNetClient()` Create a TCP/SSL client
`NetServer`	`createNetServer()` Create a TCP/SSL server
`SockJSServer`	`createSockJSServer(HttpServer httpServer)` Create a SockJS server that wraps an HTTP server
`Context`	`currentContext()`
`EventBus`	`eventBus()` The event bus
`FileSystem`	`fileSystem()` The File system object
`boolean`	`isEventLoop()` Is the current thread an event loop thread?
`boolean`	`isWorker()` Is the current thread an worker thread?
`void`	`runOnContext(Handler<java.lang.Void> action)` Put the handler on the event queue for the current loop (or worker context) so it will be run asynchronously ASAP after this event has been processed
`long`	`setPeriodic(long delay, Handler<java.lang.Long> handler)` Set a periodic timer to fire every `delay` milliseconds, at which point `handler` will be called with the id of the timer.
`long`	`setTimer(long delay, Handler<java.lang.Long> handler)` Set a one-shot timer to fire after `delay` milliseconds, at which point `handler` will be called with the id of the timer.
`SharedData`	`sharedData()` The shared data object
`void`	`stop()` Stop the eventbus and any resource managed by the eventbus.

  - setTimer
```
long setTimer(long delay,
            Handler<java.lang.Long> handler)
```
    Set a one-shot timer to fire after delay milliseconds, at which point handler will be called with the id of the timer.
    
    Returns:
    the unique ID of the timer
  - setPeriodic
```
long setPeriodic(long delay,
               Handler<java.lang.Long> handler)
```
    Set a periodic timer to fire every delay milliseconds, at which point handler will be called with the id of the timer.
    
    Returns:
    the unique ID of the timer
  - cancelTimer
```
boolean cancelTimer(long id)
```
    Cancel the timer with the specified id. Returns true if the timer was successfully cancelled, or false if the timer does not exist.

```
Context currentContext()
```
    Returns:
    The current context
  - runOnContext
```
void runOnContext(Handler<java.lang.Void> action)
```

```
boolean isEventLoop()
```
    Is the current thread an event loop thread?
    
    Returns:
    true if current thread is an event loop thread
  - isWorker
```
boolean isWorker()
```
    Is the current thread an worker thread?
    
    Returns:
    true if current thread is an worker thread
  - stop
```
void stop()
