Class org.osgi.service.component.ComponentFactory

Examples of org.osgi.service.component.ComponentFactory.newInstance()

org.osgi.service.component.ComponentFactory.newInstance()
Create and activate a new component configuration. Additional properties may be provided for the component configuration. @param properties Additional properties for the component configurationor {@code null} if there are no additional properties. @return A {@code ComponentInstance} object encapsulating the componentinstance of the component configuration. The component configuration has been activated and, if the component specifies a {@code service} element, the component instance has beenregistered as a service. @throws ComponentException If the Service Component Runtime is unable toactivate the component configuration.
