33 * \brief Base class for all component instances.
35 * This is an abstract class that must be specialized in runtime.
36 * Specialized classes must provide implementation for loading of
37 * a component (load method) unloading (unload method) and an
38 * information method (isLoaded) about the state of the component
40 * A component instance is used by one or more ServiceNode to execute
41 * services of this component instance

121 * A runtime can provide several implementations of a component instance.
122 * Each implementation has a different kind. A ComponentInstance can be
123 * associated to a ServiceNode is they have the same kind.
