@ConsumerType public interface WeavingHookOSGi Framework Weaving Hook Service.
Bundles registering this service will be called during framework class loading operations. Weaving hook services are called when a class is being loaded by the framework and have an opportunity to transform the class file bytes that represents the class being loaded. Weaving hooks may also ask the framework to wire in additional dynamic imports to the bundle.
When a class is being loaded, the framework will create a
WovenClassobject for the class and pass it to each registered weaving hook service for possible modification. The first weaving hook called will see the original class file bytes. Subsequently called weaving hooks will see the class file bytes as modified by previously called weaving hooks.
void weave(WovenClass wovenClass)Weaving hook method.
This method can modify the specified woven class object to weave the class being defined.
If this method throws any exception, the framework must log the exception and fail the class load in progress. This weaving hook service must be deny listed by the framework and must not be called again. The deny listing of this weaving hook service must expire when this weaving hook service is unregistered. However, this method can throw a
WeavingExceptionto deliberately fail the class load in progress without being deny listed by the framework.
