AnnotationProvider annotationProvider)
Obtains an object indirectly, using the
MasterObjectProvider service. |
<T> T |
getService(Class<T> serviceInterface)
Locates a service given a service interface and (optionally) some marker annotation types.
|
<T> T |
getService(Class<T> serviceInterface,
Class<? extends Annotation>... markerTypes)
Locates a service given a service interface and (optionally) some marker annotation types.
|
<T> T |
getService(String serviceId,
Class<T> serviceInterface)
Obtains a service via its unique service id.

annotation. There are two cases: constructing a service implementation, and constructing
an arbitrary object. In the former case, many service resources are also available for injection, not
just dependencies or objects provided via the MasterObjectProvider service.autobuild

until
just-in-time (that is, first method invocation). In a limited number of cases, it is necessary to use such a
proxy to prevent service construction cycles, particularly when contributing (directly or indirectly) to the
MasterObjectProvider
(which is itself at the heart
of autobuilding).
If the class file for the class is a file on the file system (not a file packaged in a JAR), then the proxy will
autoreload: changing the class file will result in the new class being reloaded and re-instantiated
(with dependencies).proxy
