Defined in:
  /Users/julien/java/vertx-aggregator/modules/vertx-lang-ruby/src/main/resources/vertx/vertx.rb

## Overview

The entry point into the Vert.x Core API.

You use an instance of this class for functionality including:

- Creating TCP clients and servers
- Creating HTTP clients and servers
- Creating DNS clients
- Creating Datagram sockets
- Setting and cancelling periodic and one-shot timers
- Getting a reference to the event bus API
- Getting a reference to the file system API
- Getting a reference to the shared data API
- Deploying and undeploying verticles

Most functionality in Vert.x core is fairly low level.

To create an instance of this class you can use the static factory methods: #vertx, #vertx and #clustered_vertx.

Please see the user manual for more detailed usage information.

## Class Method Details

### + (`void`) clustered_vertx(options = nil) { ... }

This method returns an undefined value.

Creates a clustered instance using the specified options.

The instance is created asynchronously and the resultHandler is called with the result when it is ready.

Parameters:

- options (`Hash`) (defaults to: `nil`) —
  the options to use

Yields:

- the result handler that will receive the result

Raises:

- (`ArgumentError`)

### - (`void`) execute_blocking(blockingCodeHandler = nil, ordered = nil) { ... }

This method returns an undefined value.

Safely execute some blocking code.

Executes the blocking code in the handler `blockingCodeHandler` using a thread from the worker pool.

When the code is complete the handler `resultHandler` will be called with the result on the original context (e.g. on the original event loop of the caller).

A `Future` instance is passed into `blockingCodeHandler`. When the blocking code successfully completes, the handler should call the Future#complete or Future#complete method, or the Future#fail method if it failed.

Parameters:

- blockingCodeHandler (`Proc`) (defaults to: `nil`) —
  handler representing the blocking code to run
- ordered (`true`, `false`) (defaults to: `nil`) —
  if true then if executeBlocking is called 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

Yields:

- handler that will be called when the blocking code is complete

Raises:

- (`ArgumentError`)

### - (`Fixnum`) set_periodic(delay = nil) { ... }

Set a periodic timer to fire every `delay` milliseconds, at which point `handler` will be called with the id of the timer.

Parameters:

- delay (`Fixnum`) (defaults to: `nil`) —
  the delay in milliseconds, after which the timer will fire

Yields:

- the handler that will be called with the timer ID when the timer fires

Returns:

### - (`Fixnum`) set_timer(delay = nil) { ... }

Set a one-shot timer to fire after `delay` milliseconds, at which point `handler` will be called with the id of the timer.

Parameters:

- delay (`Fixnum`) (defaults to: `nil`) —
  the delay in milliseconds, after which the timer will fire

Yields:

- the handler that will be called with the timer ID when the timer fires

Returns:

- (`Fixnum`) —
