public class Launcher
extends io.vertx.core.impl.launcher.VertxCommandLauncher
implements io.vertx.core.impl.launcher.VertxLifecycleHooks
main()
class that can be used to create Vert.x instance and deploy a verticle, or run a bare Vert.x instance.
This class is used by the vertx
command line utility to deploy verticles from the command line.
It is extensible as "commands" can be added using the CommandFactory
SPI.
E.g.
vertx run myverticle.js
vertx my-command ...
It can also be used as the main class of an executable jar so you can run verticles directly with:
java -jar myapp.jar
commandByName, lookups, main, PROCESS_ARGS
DEFAULT_ARG_NAME, DEFAULT_DESC_PAD, DEFAULT_LEFT_PAD, DEFAULT_LONG_OPT_PREFIX, DEFAULT_LONG_OPT_SEPARATOR, DEFAULT_OPT_PREFIX, DEFAULT_USAGE_PREFIX, DEFAULT_WIDTH, optionComparator
