org.rhq.core.pluginapi.inventory.ResourceDiscoveryComponent
The plugin component that defines how resources are discovered. If an implementation of this interface declares its resource component T, that means that discovery component implementation can discover child resources for that type T parent resource. This means you can nest a hierarchy of discovery components that mimic the resource type hierarchy as defined in a plugin deployment descriptor.
For example, a discovery component that can discover JBossAS data source services would declare its type T as being the JBossAS server resource component (since JBossAS server resources can have children of type "data source service".
@param < T> the parent resource component type for those resources discovered by this discovery component @see ClassLoaderFacet
