Class ResourceObjectFactory<T>

java.lang.Object
  org.apache.tuscany.sca.implementation.java.injection.ResourceObjectFactory<T>

All Implemented Interfaces:

ObjectFactory<T>

public class ResourceObjectFactory<T>
extends java.lang.Object
implements ObjectFactory<T>

Resolves a runtime resource to be injected on a field or method of a Java component type marked with Resource. If the mapped name of the resource is an absolute URI such as sca://localhost or jndi://localhost the host container namespace is searched; otherwise the URI is assumed to be relative and the parent composite is searched. If a mapped name is not provided, i.e. resolution is by type, the parent composite is first searched followed by the host namespace.
