Class Factories

java.lang.Object

net.kuujo.vertigo.util.Factories

public final class Factories
extends Object

Factory utility.

This helper class should be used with the Factory annotation to construct types from annotated factory methods. Specifically, when constructing types that are specific to different cluster modes, the factory utility will automatically fall back to the appropriate default local- or cluster- type according to the current Vertigo cluster mode.

Method Detail

createComponent

public static Component createComponent(org.vertx.java.core.Vertx vertx,
                        org.vertx.java.platform.Container container)

Creates a component instance for the current Vert.x instance.

createObject

public static <T> T createObject(ClusterScope scope,
                 Class<T> clazz,
                 Object... args)

Creates an object for the current cluster scope.

This method will create a cluster-scope specific object based on an abstract type. The abstract type must define its concrete local and cluster implementations using annotations.

Parameters:

scope - The scope in which to create the object.

clazz - The abstract type from which to create the object. This type should define concrete implementations for each cluster scope.

args - Factory method arguments.

Returns:

The created object.

resolveObject

public static <T> T resolveObject(ClusterScope scope,
                  Class<? extends T> clazz,
                  Object... args)

Creates an object for the current cluster scope.

This method will create a cluster-scope specific object based on a concrete type. If the concrete type is not supported by the given cluster scope then the factory will fall back to the default implementation for the current cluster scope.

Parameters:

scope - The current cluster scope.

clazz - The concrete type to attempt to construct. If the type is not valid for the current cluster scope then a different type may be constructed.

args - Factory method arguments.

Returns:

The created object.
