Method Detail

getOSGiComponentInstanceOfType

@Nullable
public static <T> T getOSGiComponentInstanceOfType(Class<T> clazz)

Returns an instance of the service identified by the given interface, as exported by a plugin module.

Warning: as the instance returned comes from OSGi-land, it can become invalid at anytime (if the plugin is disabled/enabled for instance). For this reason, it should NEVER be cached (e.g stored in a field variable).

Type Parameters:

T - the interface type

Parameters:

clazz - the interface of the service

Returns:

an instance of the service, or null if no plugin publicly exports this particular service.
