Package io.reactiverse.es4x

Class ESVerticleFactory

java.lang.Object

io.reactiverse.es4x.ESVerticleFactory

All Implemented Interfaces:

io.vertx.core.spi.VerticleFactory

Direct Known Subclasses:

JSVerticleFactory, MJSVerticleFactory

public abstract class ESVerticleFactory
extends Object
implements io.vertx.core.spi.VerticleFactory

An abstract verticle factory for EcmaScript verticles. All factories can extend this class and only need to implement the 2 abstract methods:

• createRuntime(ECMAEngine) to create the runtime where scripts will run
• createVerticle(Runtime, String) to create the verticle that wraps the script

public ESVerticleFactory()

Method Detail

init

public void init(io.vertx.core.Vertx vertx)

Specified by:

init in interface io.vertx.core.spi.VerticleFactory

order

public int order()

Specified by:

order in interface io.vertx.core.spi.VerticleFactory

createRuntime

protected Runtime createRuntime(ECMAEngine engine)

Create a runtime. Use the method ECMAEngine.newContext(FileSystem, Source...) to create the runtime.

This method allows the customization of the runtime (which initial scripts will be run, and add/remove objects to the global scope).

Parameters:

engine - the graaljs engine.

Returns:

the configured runtime.

createVerticle

protected abstract io.vertx.core.Verticle createVerticle(Runtime runtime,
                                                         String fsVerticleName)

Create a vertx verticle that wraps the script, it will use the runtime configured in the createRuntime(ECMAEngine) method.

Parameters:

fsVerticleName - the name as provided during the application initialization.

runtime - the runtime created before.

Returns:

the configured verticle.

defaultExtensions

protected abstract String[] defaultExtensions()

Declares the default extensions this verticle factory will use when looking up for modules without extension on the filesystem.

Returns:

array of string in the format .EXTENSION

createVerticle

public final void createVerticle(String verticleName,
                                 ClassLoader classLoader,
                                 io.vertx.core.Promise<Callable<io.vertx.core.Verticle>> promise)

Specified by:

createVerticle in interface io.vertx.core.spi.VerticleFactory

setupVerticleMessaging

protected void setupVerticleMessaging(Runtime runtime,
                                      io.vertx.core.Vertx vertx,
                                      String address)

waitFor

protected final io.vertx.core.Future<Void> waitFor(Runtime runtime,
                                                   io.vertx.core.impl.ContextInternal context,
                                                   String callback)

close

public void close()

Close the factory. The implementation must release all resources.

Specified by:

close in interface io.vertx.core.spi.VerticleFactory
