Examples of org.picocontainer.MutablePicoContainer.registerComponentInstance()

org.picocontainer.MutablePicoContainer.registerComponentInstance()
Register an arbitrary object. The class of the object will be used as a key. Calling this method is equivalent to calling * registerComponentImplementation(componentImplementation, componentImplementation). @param componentInstance @return the ComponentAdapter that has been associated with this component. In the majority of cases, this returnvalue can be safely ignored, as one of the getXXX() methods of the {@link PicoContainer} interface can be used to retrieve a reference to the component later on. @throws PicoRegistrationException if registration fails.
