Examples of com.ctp.cdi.query.spi.DelegateQueryHandler

com.ctp.cdi.query.spi.DelegateQueryHandler
A marker interface. Used for writing custom query methods: public interface DaoExtension { E saveAndFlushAndRefresh(E entity); } public class DelegateDaoExtension implements DaoExtension, DelegateQueryHandler { @Inject private QueryInvocationContext context; @Override public E saveAndFlushAndRefresh(E entity) { ... } } The extension is now usable with: @Dao public interface MySimpleDao extends DaoExtension, EntityDao { }


    @Override
    public Object execute(CdiQueryInvocationContext context) {
        try {
            InvocationContext invocation = context.getInvocation();
            DelegateQueryHandler delegate = selectDelegate(context.getMethod());
            if (delegate != null) {
                return invoke(delegate, context);
            }
            return invocation.proceed();
        } catch (Exception e) {
