Class OSGiInstanceWrapper<T>

java.lang.Object
  org.apache.tuscany.sca.implementation.osgi.runtime.OSGiInstanceWrapper<T>

All Implemented Interfaces:

InstanceWrapper<T>

public class OSGiInstanceWrapper<T>
extends java.lang.Object
implements InstanceWrapper<T>

InstanceWrapper for creating instances for OSGi components. This class needs to implement InstanceWrapper since the wrapper is stored in the scope container. But getInstance() is called on this wrapper only through the OSGi target invoker. OSGiTargetInvoker always invokes getInstance for a specific service since one OSGi SCA component can associate different objects with different services (this is different from Java SCA components which always associate a single component instance with multiple services).
