Example 1 with Interceptor

use of org.apache.aries.blueprint.Interceptor in project aries by apache.

the class BeanRecipe method addInterceptors.

private Object addInterceptors(final Object original, Collection<Class<?>> requiredInterfaces) throws ComponentDefinitionException {
    Object intercepted = null;

                    b = blueprintContainer.getBundleContext().getBundle();
                }
                intercepted = blueprintContainer.getProxyManager().createInterceptingProxy(b,
