public interface OpenWebBeansPlugin

Interface which all OpenWebBeans plugins have to implement to extend the webbeans-core with additional IOC functionality.

2. injection execution will be called every time a been get's injected like #injectResource(Type, Annotation[])

Method Summary

<T> T	getSupportedService(Class<T> serviceClass) Gets service instance.
void	isManagedBean(Class<?> clazz) Make sure that the given class is ok for simple web bean conditions, otherwise throw a WebBeansConfigurationException
void	shutDown() At shutdown, the plugin must release all locked resources.
void	startUp() initialise the plugin.
boolean	supportService(Class<?> serviceClass) Returns true if plugin provides given service implementation false otherwise.
boolean	supportsJavaEeComponentInjections(Class<?> targetClass) Returns true if given class supports injections, false otherwise.
