Class ReflectionServiceResolver

java.lang.Object

org.mule.runtime.module.service.internal.discoverer.ReflectionServiceResolver

All Implemented Interfaces:

ServiceResolver

public class ReflectionServiceResolver
extends Object
implements ServiceResolver

Resolves Service instances given a set of ServiceProvider instances.

Resolution process consist if find, for each service provider, all the service dependencies it has. Then, service providers will be instantiated when the required set of dependencies is available.

Resolution of services providers must be done always in the same order for the same set of providers to ensure a consistent startup of the container.

In case of a missing dependency, the resolution will fail and the container should not start.
