injectMembers
Description copied from interface:Injector
Performs field injection on a given object, ignoring constructor injection. Since Cayenne DI injector returns fully injected objects, this method is rarely used directly.Note that using this method inside a custom DI
Provider
will most likely result in double injection, as custom provider is wrapped in a field-injecting provider by the DI container. Instead custom providers must initialize object properties manually, obtaining dependencies from Injector.- Specified by:
injectMembers

shutdown
public void shutdown()Description copied from interface:Injector
A lifecycle method that let's the injector's services to clean up their state and release resources. This method would normally generate a scope end event for the injector's one and only singleton scope.
